About 2 months ago, I had a real bad cough and heavy congestion, and the doctor prescribed a cough syrup with codeine in it. Two weeks after I finished the medicine, I started itching on my legs, from the thigh down, and also on my arms. I tried taking benadryl for a couple of weeks, that didn't help. I also take medicine for herpes. I am a 47 year old female. Do you think hydrocortisone creme will help, or will I have to take oral medication. I tried taking a z-pack prescribed by my doctor, that didn't help either. My skin seems to be very, very dry, and the itching is very iritating.
