If you had a blood clot the pain wouldn't come and go. It sounds sound a bit like nerve pain, the shock sensation. Unpleasant as that is it will go away on its own. Stop worrying about it, stop moving your leg around to see if you can still feel it (I'm guessing you're doing that, apologies if you aren't, but it seems like a lot of people with blood clot worries seem to spend a lot of time seeing if it still hurts!), it'll probably sort itself out.
