I have had 2 pulled muscles in the last 7 or 8 weeks. The first was in my left upper shoulder, now it's my left lower back/sciatic nerve area. I did not do anything strenous to hurt these areas, but it's a symptom (possibly) that I've never had b4, nor my husband, who has been getting treated 4 Lyme a lot longer than me. Anyone else with this problem, or thoughts?
