Hi there, i just consulted a physical medicine doctor regarding my right lower back pain that i am experiencing for almost 2 weeks now. At first it was just a back pain that shoots everytime i bend forward but now i could feel that the pain is extending to my groin that i can describe as burning pain. My pain is worst at rest and is relieved with movement. The pain doesn't bother me since i have a high pain tolerance but what scares me is that when the doctor tested my reflexes on my first visit, my ankle reflexes are both absent and my right knee jerk is also absent. My left knee jerk is there. The doctor asked me if i lifted any heavy object or is there any injury that happened prior to my symptoms, and there is none. I just woke up one morning and i feel pain every time i bend forward. There is no numbness or bowel or bladder disturbances aside from pain. I did xray to check if there is anything wrong with my spine but the result says mild narrowing of l5 and s1 that is due to muscle spasm. I also did blood chemistry and the doctor checked my thyroid hormones since he said the lost of ankle reflex maybe because i have hypothyroidism but my thyroid hormes are completely normal. He prescribed 600mg iburopen for pain relief which was not effective anyway. Heasked me to come back after 2 days for follow up. When i came backfor follow up. He did the reflex exam again and got the same result, negative right and left ankle reflex, but now both my right and left knee does not have the knee jerk reflex. He also checked my upper limbs reflex that is completely normal. The doctor finds it wierd that my upper limbs have reflexes and my lower limbs don't. And the pain is still there, so he injected lidocaine at my back to relax my muscle but i find it not effective as well since i still felt the pain everytime i bend forward and the burning pain in groin is still there. I asked him what could be the possible reason for my lost of reflexes and he said it could be disc lesion but he will not consider it a severe or serious case unless i manifest other symptoms aside from pain. But i still want a clear answer on why my reflexes are gone and why do i still pain? If there is anyone here who experienced the same symptoms as me, it will be a really great help. Thank you.
