Hello, I have developed a rash on my chest. I feel feverish and have been using apple cider vinegar, cold compresses, and acyclovir ointment. Other outbreaks have been occurring on leg and foot. I don't know if it's shingles or an allergic reaction. I have had a shingles shot but over 5 years ago. I'm diabetic and take medicines low-dose aspirin, rosuvastatin, losartan, invokana, lantus, anora, and vitamin D. I'm 74 years old and have been under stress. Can I take a higher dosage of aspirin for temporary relief? I'm female.
