Hello. I have this lump on the side of my thigh. Its about the size of a tennis ball. (if you were to take the tennis ball in half, that would be the size of my lump) there s no discoloration on the bump, although my leg, ankle and foot appears to get pale at times. The lump on the lower side of my thigh is warm to touch, there s no pain when I push on it though. I ve noticed since I saw the bump, my leg, foot and ankle gets a sharp pain. The pain is kind of like a thumping pain. (pain is here one second, gone the next and then back again. Process continues over and over again, not sure the proper term for that, that s why I said thump) my leg also feels at times like it cramps up, and it only use to happen every now and then but it s happening more often now. My leg also feels heavy it times this just started happening though. I also noticed that my leg, ankle and foot gets swollen on a daily basis, whether im relaxing or actually walking. I first thought it was an internal bruise, but this is the third week with this, and symptoms seems to get worse instead of getting better. I need a doctors opinion before i go to my doctor and pay a bill for something that may be not that serious.
