Hi, You have pins and needles and weakness of the leg which points to a nerve problem in the back.  If you have a slipped disc then this could compress the nerve and cause the above condition. You could also be having sacroiliac arthritis in addition, but most back pains with disc protrusions can appear to be from the sacroiliac area. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
