I might have to have my perm stem in my lower back removed! I'm having bad headaches and chest pains and they can't seem to find the reason why! They can't find any leaking so they think that my body is just not excepting my stem. On top of my nerve pain and leg pain now I have all of this other stuff going on. If I had to do it all over again I would! I just wish this would have worked for me. I would rather have my old pain back than all this new stuff! My stem has been in since April and hasn't worked right from the start. The trial was great but, the perm never has been right. Like I said I would do it all again because I feel if I didn't try then I wouldn't know if it would have worked or not! I have one more visit with my neuro before they say take it out. It's up to him. Well I'm done going on just needed to vent a little so this is my outlet! Thanks for listnening!
