He adds that he does not get high fevers so he thought he had like allergies but it was not so, and he had cold spells. He did not have a fever. The skin on his left hand felt funny when he was touching it, it was almost painful. Like, when someone touches their hand it feels okay but this almost felt painful to touch. It was his left hand. It was his left shoulder almost close to his neck where the red spot was. Saturday, he saw the spot and felt symptoms. He thought maybe he touched something, or something bit him. Sunday, the symptoms did not go away. He started feeling worse, feeling sick but not a fever. He said it persisted until Sunday. By Monday morning, because his wife is a daycare director, he told her he got sicker and not to go because he felt sick and he did not know if he had COVID or he did not know what he had. They went to the clinic to make sure it was not COVID. He got tested for COVID, but also told them he discovered the red spot and he had symptoms. They tested him for COVID and it was negative. The doctor looked at the red spot and saw his symptoms and said that patient has shingles. He then was diagnosed with shingles and was given medication for it.

The doctor told him to take Advil. He usually takes it in the morning, and then if he starts to need it because shingles can make people feel cold and flulike symptoms from the shingles.

It gets muscles tight and that creates pressure. It is hard for him to lay down and sleep because of the shingles. He wanted to know if this is a normal reaction with the vaccine and if he should still receive the 2nd dose, and what he should do next.
