He talked to the local people giving the vaccine and they recommended he still get the second dose even though the rash was going on. He went to a medical facility. He had been there before. They gave him an injection of Medrol and seven days of Medroxy Prednisolone tablets. That helped a lot, but then he got the second shot. He continued to have itchy rashes all over his body. He went back to the medical facility and they gave him a dose of Decadron steroid and another seven day package of Prednisolone. He called a dermatologist that he saw a couple of years ago. He couldn't get caller in and caller had a feeling he didn't want to deal with it. Caller got an appointment with another dermatologist and went to the office. He was seen by a PA.
