For the last 2 months I have had increasing pain in my lower back down my left leg to my toes. It is complicated by a feeling like hitting your elbow, “funny bone.” This occurs constantly with sudden increasing intensity even when sleeping. There is no relief from this walking, sitting, standing or laying down. Ibuprofen doesn’t affect the pain level. 2 years ago I had a similar but lesser pain which was treated with shots in my back. They had no effect. This pain with additional syptoms is affecting my quality of life and my ability to function. I have an appt. with my doctor in 3.5 weeks. Appreciate any possible answers.
