He clarifies that he woke up shaking like a leaf and took some Tylenol and was very tired, he went to work for a half day. No further details provided about the Tylenol he took. He says he was very tired, and then the headache started Saturday morning, he couldn't move his neck and his head felt like it was going to explode. He says he had fever and chills, and was going through 4 sets of clothes at night, he was even sleeping on towels because he was sweating so much. He says his fever fluctuated from 101.2 to 102.4 over four days. He says he just ate soup and drank water. He says he had the fever and was sweating and kept changing clothes. He says he felt like his head would explode and he couldn't move his neck, he was one step from going to the hospital, but he didn't want to go to the hospital, and kept talking to his doctor about this. He says on day 7 his fever came down to 101, and day 8 he had a rash and welts to his head and scalp, he couldn't brush his hair. He says the rash went to his body, his back and arms and face. He says that the welts were on his head. He says that the welts lasted a day and a half. He says that the rash went away some, on day 9 he was rid of his welts to his face and head. He says that the rash to his face and back slowly went away, but stayed on his arms and hands until day 20. He says on his scalp he couldn't touch his hair. He clarifies he broke the fever after day 9, and on day 10 his rash started going away except on his arms and hands. He says when he had the fever and chills he was shaking like an earthquake. He say that the headache felt like if he coughed his head would explode, he felt glad he didn't sneeze, that really might have done him in, there was so much pressure. He says he lay in bed in pain until he got tired from the pain and slept. He says that on day 20 the rash just went away, and his hands now have the skin peeling away, he doesn't know if anyone else went thru this. He says he has been putting lotion on his hands, but his skin is peeling away like crazy, he would like to know if anyone else has been going through this. He says now there is supposed to be a booster shot every 6 months after getting the two doses, they would have to convince him to get booster, he is a really healthy guy,and this put him in bed for a week. He says if this is what the treatment feels like to prevent getting the disease, he would hate to actually have it. He says when he talked to his doctor they had told him if his symptoms lasted one more day to go to the hospital. Caller clarifies that until day 20 he had the rash to his arms and hands, then day 20 it finally subsided and his arms and hands welts and rash disappeared, and now his skin is peeling away everywhere.
