numb penis after back surgery at L4-L5-S1

first of all sorry for my bad English!

8 months ago I underwent spinal surgery (stabilization L4-L5-S1), because of spondylolisthesis at L5-S1 12 mm. forward slippage.
Now I have more tingling in the feet than before surgery, but there is one thing that bothers me more.
After surgery the right half of my penis was numb and is still numb.
I also have a numb strip on the back of the right leg.
Perhaps there is minimal improvement, but it is minimal for 8 months.
After surgery I have made two radiographs after the third month and after the seventh month.
My surgeon is not particularly impressed by my complaints and when he examine radiographs, he said that everything looks normal and told me to wait another month and then to do MRI.
I think my nerve is damaged during the operation.
What can I do more?
MRI + EMG ??

Thank you for your attention!

    Sorry for all you're going through. It's so frustration.
    I have not had surgery myself, so not first hand knowledge...but I understand that the healing can take quite awhile and is different for everyone.
    Sometimes longer for some people.

    It's good you continue to talk to your doctor about all your symptoms and continue to tellto him each time you see doc.

    For me personally, EMG was best test, most revealing to the doctor for ...oh, look at that..kind of thing. It gave him answers and a game plan for my pain management.

    But I don't know, you may be healing at acceptable rate. But let's face it...some numb areas can be tolerated a little better than other, so I certainly understand your concern.

    Maybe others here have more experience and ideas. I would think it doesn't hurt to ask doctor about Emg, as you said.

    I wish you the best and please let us know how you are doing.

  • I have just recently developed numbness in my left side of my butt and down my leg and into the foot at times. My butt area always feels numb and the other comes and goes. No pain like before so I'm dealing with it much better. Dr. told me this week to give it a couple of months and if it's still bothering me then he would do another MRI and see if anything shows up. I feel your concerns.

  • You've gone through a major surgery. Nerves have been cut and it takes time for them to grow and regenerate. I know, I had certain areas of my abdomen that were totally numb along with other areas. My physical therapist told me feelin usually comes back after time. Most of the time. Mine has been coming back in some areas and it's been over 3 years since surgery. But do mention all your symptoms to your dr. Good luck, Kevin
  • Thank you for your answers.

  • Have you tried puting heat or ice on the penis see if that helps? Maybe a massage therapist might help, I know they have scs for spine stimulater not sure if they have a penis stimulater other then what they sell at the adult stores,


    There is a nerve maping that shows what nerves go to what area of the body, I am not positive but i think its levels l2l3 or l3l4 that controls sexual organs,

    But of course all the nerves are connected so very posible your surgery agrivated many nerves and will take some time to calm down and be back to normal,

    I dont think its unusual to have less feeling there with anyone who had back surgery or anyone who has pain, I would worry only if it stoped working all together,

    Best of luck with your recovery,

  • Until this moment I have only reduced sensitivity in these areas and I do not feel temperature sensation.
    If I put and hold for some time something hot or ice then I feel pain.
    Soon I will make MRI and EMG.

    Thanks for all advice .
  • I did MRI,EMG and I talked with another neurosurgeon last week.
    When he examined MRI he said that one of the screws of L4 is placed incorrectly.
    Something like this but he said that bad screw placement is not related to my less feeling and re-operation is unlikely to improve symptoms.
    He confirmed my fears that the nerve is probably injured during the operation.
    He was optimistic about my condition and said that it is possible regeneration of affected nerve up to two years.

    I would say that I'm quite disappointed by my surgeon because he is not honest with me and hold me so long to wonder about my real condition.
    He also lied me that he had performed a reduction of the listhesis. X-rays images show clearly no reduction.

    My radiographs comparison before and after surgery here and here.
    My MRI Before surgery
    My MRI 8 months post-operative

    When I asked him about adjacent segment degeneration after an L4-L5-S1 stabilization he told me that " there is no risk because l5 is natural immobilized at level L4 screws are polyaxial and preserved mobility of the vertebrae ".
    As far as I understood from the Internet polyaxial screw has nothing to do with dynamic stabilization.
    I wonder where is the truth?

    About EMG I tried to make a translation in English.
    There are specific terms but here it is.

    The speed of conducting of motor and sensory nerve fibers of the researches of the feet is normal.
    The percentage of F-waves for l4-l5 is reduced bilaterally and slightly prolonged latency to S1 bilaterally.
    H-reflex of the M-RECTUS FEM DEX occurs with normal parameters.
    H-reflex of M.SOLEUS SIN. is on upper limit of normal from M.SOLEUS DEX occurs with increased amplitude.
    Conducting a N.FEMORALIS DEX and amplitude of M-responce are within normal limits.
    EMG evidence for the root damage at L4, L5, S1 bilaterally, more pronounced for the L4, L5.

    ...about where is the truth?

    Everyone is individual, but my experience surgeons not real talkative unless they get to do surgery. And I think a little on the arrogant side...but if I need to have surgery, I guess I would want someone who felt pretty sure of himself.

    And where is the truth? I dont know how docs decide what to say and not say. So many times I pick up my records for consult..and look through the records and find many things that no one has ever told me.
    I don't understand it either...so you definately not alone there.

    Sadly, I've come to expect that..but I just deal with what I know as it happens...just as you are doing now.

    I know nothing of the readings of your EMGs, but wish you nothing but the best as you go forward in taking care of yourself.

  • It may not hurt to have a consultation with a Urologist. There actually are therapist who are trained to deal with the issue you have with numbness in your private area. You may need to do some checking to find one because not all PT's deal with this issue.

    After I had my ALIF in 07, I had to begin using Viagra to be intimate with my wife. It was all tied back to surgery. One of my PT's recommended another PT that worked with issues such as this. Unfortunately, my WC wouldn't cover it as it was deemed specialized.

    I also had a lot of numbness in my left leg after surgery. It took a long time to go away, but now my leg is fine. I'm still numb all around my abdominal incision though.
