HIVES.....I know this is a strange question but I have done everything I know so maybe being out of afib is the cause.....at night when I crawl into my comfy bed,,,,sometimes I break out in hives all over my body. This started after my 1 st abalation and now after my 2nd abalation I have not had any rapid beats. I have had the same bed for years. Same soap, same everything and it only happens about twice a week. I am out of options. Could it possibly Have been something about the abalations. It doesn't happen during the day. I know it sounds crazy but nothing in my life has changed except abalation.
