I only just posted a little while ago for god sake!! lol anyway randomly got a deep pain behind my knee so had a look and theres swelling!! quite obvious swelling too, got an app at 5 and know this can be bakers cyst but of course I also know you can get a blood clot there too :( so yes im panicking and I have to wait till 5 for an app, I asked the assessment person if it sounded like a clot and he said not at the moment but wait and see, hmm yeah that was helpful lol
