Yesterday morning I noticed pain in my left buttock, and again this morning when I awoke. I am a cashier at Michaels Arts and Crafts, and worked 5 hours today on my feet . When I got home from work, my pain left my buttock and is now very painful in my upper inner left thigh, and has started to turn red in an area on my inner left thigh. I have taken 2 aspirins and have traded off ice pack and heat pad, and the pain feels as if it s trying to weaken. What is going on with me? Please help. Thank you!
