M18. Health anxiety. I am already on Sertraline and I'm with a psychotherapeutic. 
I think about my legs and a possible blood clot there every single second for about 2 months now. It feels like I am waiting for a pulmonary embolism. I neither have a single risk factor, nor any specific symptom. My legs just feel 'weird'. Sometimes I can feel some tension whether in the backside of my knee or around the ankle aswell as right and left of my foot. So basically all in my legs some sensations would I call them. I don't have pain when I use my legs, just the named tension/sensations. I can't get rid of my thoughts and anxiety. I already made a list of 10 things that speak against a DVT/blood clot but I am just so fixated. What can I do? I have already been to a vein specialist but he only checked my left leg, now the focus is in my right leg. I don't want to go to my doctor again, I go there like every 2 weeks.
