I am 22 5'5'', 11st 5lbs. I have already had a ecg, chest x-ray, d-dimer test few months back. Last week I got a MRI scan on my lower legs because I am so scared and terrified of getting a blood clot. I have been doing a lot more walking around lately, even to walking my dogs. I get this little nagging cramp in the back of my right calf. And I read that a simple cramp is a blood clot and that there are no symptoms, until it goes to your heart and kills you!!! so freaked out right now. I am waiting for my scan results no news is good news I suppose. But I am so frightened of blood clots I cry with fear. I am on anti-depressants for the last few months simply down to my fear of having a blood clot, please help...does it sound like I have one?I am 22 5'5'', 11st 5lbs.
