[|Human|] Hi , Wednesday evening i had a tender groin and a little swelling at the groin/top of thhigh area with redness. By the next morning the redness had started to go down my leg and it has been itchy and warm with some swelling where it is red . It also feels like i have a thick hard vein? Or something like that going down from top of thigh to where the redness stops . It was still a little red this morning and i thought it was going but by late afternoon it s started to get itchy again . It is warn to the touch . I got bitten by something on Tue afternoon on my calf and by wed morning and my calf was very swollen but that seems to be less hard and swollen today . Wondered if it was to do with the bite . Thanks Angela
[|AI|]  Hi, Angela. Certainly this could possibly be related to the bite, but there are 2 other possibilities that require prompt evaluation. One of these is a blood clot in the deep veins of your leg. This can create swelling, redness, heat, and pain. An infection in the skin can create similar symptoms and eventually spread into your blood. If you are still having any of these symptoms or the thick hard vein, get checked at an urgent care center or emergency right away. An untreated blood clot or infection like this could progress into a life-threatening situation. Hope this answers your query. If you have further questions, I would be happy to answer them.
