You may want to talk to your Dr, about looking into a different Beta-blocker, I started with Verapmil, which was not a good fit, then Coreg CR ER the brand that worked for 17 years till the manufacturer changed and now it's packaged as the brand Coreg CR but is actually a generic Carvedilol which gave me severe rashes that simulate burns marks all over my body, I now have scarring and severe hyperpigmentation. If you are feeling skin burning please have your doctor look into that immediately. Apparently, Beta-blockers can cause these reactions, I had blood work that revealed toxic levels of neutrophils. My former cardiologist, who I am seeing again changed me over to Bystolic, which seems to be a much better fit for my Myocardio-bridge. Hope you feel better soon, and be well.
