I've Been Not Feeling Well Lately. I Have Had 6

I've been not feeling well lately. I have had 6 stents in my heart in the last 4to 5 years. Lately, I am very tired. I am having a lot of pain in my joints. The weirdest symptom that I am having is a sensation in my legs as if they are about to go to sleep. Kind of a nerve thing, sort of tingly feeling, sort of numb from my thighs to my ankles. I am also having a lot of anxiety.
