I have a very swollen ankle and calf it's very tender to the touch and it gets like this if i stand or walk could it be a blood clot in my ankle?

Evaluate ASAP.: There is, most certainly, a high degree of suspicion for a blood clot. There are other possibilities, but none with the devastating potential results of a clot. Your next move should be to an urgent care clinic to remove all doubt. It might not be wise to over think this. Have the leg evaluated ASAP.

Sore ankle: Not likely but if I knew your age and if you were on BCPs I could give better help. Discuss with your Dr. You can never give me too much information.
