For about a week or so now I've been having an odd pain deep in my left thigh. It's not excruciating by any means. It feels a little like I pulled something but I haven't done any exercise or movements that would really result in that. The pain comes and goes. Sometimes it shows up when walking. Other times when laying in bed or sitting. No visual abnormalities on my thigh. Thigh is not warm to the touch. No tingling, itching, numbness. Just the pain. About a 2 on a 10 point scale (10 worst pain ever). Any hint at what this could be? My pessimistic mind says Deep Vein Thrombosis, but I would imagine that would be much more painful. Thoughts?
