A blood clot can be serious if it moves, it can cause stroke. Have you been to a MD and had it checked out? I have had blood clots, some of which were harmless and eventually went away, and then I had occassion to develop a blood clot from the car door hitting my leg and had to take anti-coagulants to disolve the clot. Please have it checked out - it may seem like an inconvenience or an unecessary expense, but it is better to be on the safe-side, don't you think? I hope it is nothing. Good Luck.
