question: Hi, may I answer your health queries right now ?  Please type your query here... Hi, i have a question, I was just release from the hospital with a blood clot. It was located on my right leg in the upper thigh part. I had to take a long trip and while on my trip my right upper butt has knot and is warm to touch and hurts very badly. I was wondering if it could be a blood clot. It hurts to walk sleep and bascially anything I do.
