I have had terrible health anxiety for the past few months and am not sure if this is just another episode of that anxiety or a reason to worry....
I am overweight and been having issues with tendonitis in my left foot for a few weeks now. Last night I started getting pains in my calf and up my leg and when I had a look at my leg, the left calf is visibly bigger than the right calf. I have no idea if its swelled up or if there was always a difference but now I've got myself worried that the swelling and pain is due to a blood clot 
I don't have any redness or heat in the area and I'm sure they're also symptoms, so don't know what to do. Do I just leave it and see if it gets better, or do I start panicking?
I hate health anxiety...never know what's real or when to genuinely worry
