I have been battling a rash and hives since August. I have bumps and whelps all over my body. My meds are amitriptyline 25 mg, nexium 40 mg., zetia 10 mg, gabapentin 100 mg, gemfibrozil 600 mg, losartan 25 mg, metformin 500 mg. I have been to Duke Dermatology and Regional Dermatology and no one has any suggestions or answers.
