I am 80 years old, have type 2 diabetes - taking Metaformin pills, heart disease and high blood pressure. Developed symptons of swollen vagina, thighs and lower abdomen, pink non raised rash, really bad burning sensation. Cool tub water soothes, but only for little while. Said it might be allergic reaction to something, but I do not think so. Taking Benedryl, however have now developed fever. Any ideas ?
