A few days ago, I developed red, sore areas in the bottom of my mouth between my teeth and lips. Then I developed this red/pinkish area around the areola on my breast and extending about 1.5" . The spot on the areola is sore to the touch but does not feel like a lump. I have been taking a lot of the generic brand for Sudefed PE Cough & Cold medicine and then Alka-Seltzer Plus Cold Medicine in the last few days. Could these areas be possible side effects for too much medication? That is the only thing that I can relate to these 2 items happening at the same time.
