Hi, I Could Feel Something Move Thru My Leg From

hi, I could feel something move thru my leg from arch of my foot all the way up to my groin. as it got into my calve it started to pain, worst pain I have ever had and 2 torodol pain killers would not kill the pain. was it a clot moving thru my leg that I felt. about 10 days previous to this I injured my ankle at work. last Thursday I was hospitalized because doctors thought I possibly had a clot.
