Hi Dr. Christensen. My mom, aged 70 had a heart attack one week ago today. She had a 100% blockage of the left front artery leaving her heart. A stent was put in and she s doing fine. Right now she is experiencing a terrible and painful rash. She likenens it to shingles (she was vacinated against them and has never had them) as this is what she imagines it would feel like. We think it s an allergic reaction to Brilianta, a new drug she was prescribed. The pharmasits told us to use Benydryl but it doesn t seem to be working. We have moved up her appointment date with the heart specialist as her family doctor doesnt want to change her meds. Any suggestions?
