I have had minor back pain on and off for several years and usually a few Ibouprofen & the heating pad and it goes away. For me the pain started on 4/11/13 and I was treating with the above mentioned methods. Went to GP on April 4/22 who did nothing more then give me a prescription Ibouprofen and set me in for physical therapy. The prescription did not help but the physical therapy was helping some. I called GP a week later 4/22 and said the meds are not working asked for something else. GP prescribed ophenadrine which also did nothing for pain. Woke up on 5/06 in so much pain that I was sick to my stomach and it was then that my left foot went numb. Called GP who set me up for x-rays which according to GP showed arthritis and GP prescribed a muscle relaxer which did nothing but make me sleepy. A day later no relief from pain and foot is still numb finally contacted sports med doc who prescribed steroid pac and set up for MRI. Steroid pack relieved pain so that I could do PT excercises. MRI showed bulging disk had first of 3 shots today and pain has subsided (even before shots) but left foot is still numb. My ? how long will it take for the numbness in my foot to disapear if ever. I am an active woman in my late 40's and this has slowed me down considerably.
