I have a lot of swelling in both legs and am retaining a lot of fluid. I was working at my desk for a good part of the day and did not get up to often. I felt my pants tight against my leg so I went to the bathroom to look at my legs and they were 1.5 times larger than normal. My left knee near main vein is blue bruised, however I did not hit anything and it was warm earlier and tender to the touch however is relieved when elevated, it is no longer warm, however still a little tender. It started about 6 hours ago. It is still slightly I have had my leg elevated most of the time since 2 pm. However was not sure if I had a blood clot. I am also having a lot of immune issues currently and will be going in for a bone marrow check because many of the tests currently ran on me are coming up negative. I have been swelling in many other parts of my body also. Just trying to figure out if I should go to urgent care.
