For the past year or so, occasionally I experience a very painful aching in one of my legs. I think it is always the right one, but I can't remember specifically. It is not fixed to one spot, just my whole thigh above the knee. I noticed that it lasts around 2 or 3 hours, then the pain kind of moves downwards and just stops. It always starts when I am in bed trying to sleep. I don't even notice any swelling, or redness or anything like that, just a very painful ache. I initially though it could be a blood clot, but I assumed that with that, the pain likely wouldn't just go away so quick. I'm not really sure what else it could be, because it's not associated with any other symptoms, yet it does really hurt so I figure it has to be something. Can anyone tell me any ideas they might have, and also, for future reference, what does happen when you have a blood clot in your leg? Does it basically hurt until you have it checked out and diagnosed, or can the pain come and go over a long period of time? I think I 'm getting worried more than ever recently because someone I knew passed away as a result of a blood clot which travels to her lungs. If anyone can help, that would be great
Oh, and also, while it does seem to always happen at night, it feels better if I remain lying down, it hurts more when I get up and walk around, another reason why I thought it could be a blood clot.
