I have a bump on my leg that is the size of a nickle. It hurts when I flex my leg or walk but not severe pain. Could this be a blood clot or a bursted vein???

i to have something like this on my leg it looks like a bite or bruise but i had it
for a couple of months

I wouldn't be surprised if it is a blood clott. You should have it checked out by a doctor. I had a red bump on my toe that I thought was a spider bite and the pain would come and go. The stupid thing took forever to heal so I made an appointment with my doctor and found out I have a blood disorder that causes blood clotts. Its better to be safe then sorry.
