I Went To Doctor Today And Just Not Feeling Comfortable

I went to doctor today and just not feeling comfortable with the visit. I was diagnosis last April with blood clots in my left leg and a bunch in my lung and have been taken Xarelto 20mg a day. Well had visit today to check the static of them cause last check was August and it was getting close to a year, My left leg was sloan starting Sunday really bad. Its double the regular size. When I went to doctor, he measure my legs and took blood work. He does not think its the blood clots. I don't feel good about this.
