Hi, I Have a question about an odd pain in my leg. I had it happen last night. it starts about mid thigh and heads to my groin area. Last night it was bad enough that it caused severe sweats, and pins and needles in the top half of my body. After I threw up, I called 911 and they transported. Went to hospital, and they took blood and listened to what I said. My blood work all came back ok and they sent me on my way. I am back home and my leg is still having pain, but not like last night. Not sure what to be doing or why it could be happening.
