I was in the hospital in late May from Afib. I stayed in the hospital for 4 days and then 1 more. I have DILTIAZEM 120 MG and METOPROLOL 25 MG. I also take Xarelto, but my doctor stopped it for about 3 weeks. I get fairly dark spots on my body that could pop up anywhere. I think they go away, but don t know where they come from. Also, I have new veins all over my legs and they look terrible. They came on very fast. Can you explain all of this, please?
