I started having severe pain on the right buttock last week. 3 days were terrible. Now the pain is sporadic and i just cant breath when the pain hits. Pain lasts for about 20 seconds and stops. The area is the size of half sheet of paper, only this one area, feels like the pain is directly under the skin, there is no swelling, no color change, no bumps, knots nothing that can be seen or felt. I have done no activity to cause me a problem. I have never had any issues with the hip, joint, back side etc. Idea s??
