This started about a week ago. And it started with sores on my tongue. The sore would come at night gone next morning back again that night but different spots. Yesterday. I started having sharp pains down my left leg. Felt like the nerves being pinched like when I was preg just more intense pain with it. All down my right leg. Later in day it was my right leg. Then by 8 last night I had 2 big knots on both sides of my hips. Hurt so back I couldn t walk. Went to bed next morning it was sore but not as bad. Well as day has gone by the pains were in my buttocks. Felt like the muscles needed to relax. Now I am sitting up at 2 am and have those knots in my arm where IV goes behind my ear and top of my knee. Sharp pains red and swollen up. Could this be shingles or what could it be? I m scared
