She had electrical shocks in one leg particularly the area between the hip and the knee (thigh area). She has taken prednisone. The sensation went away for a day but it came back but not as bad as before. The electrical shocks would leave her with burning sensation on her skin. Her rheumatologist didn't think it was because of the vaccine but her girlfriend told her that she has seen reports of nerve sensations after getting the vaccine on the TV. Caller wanted to know how long this adverse event would last and would it go away. The caller was calling about the Pfizer covid 19 vaccine. The caller's girlfriend called her and was watching a program on TV about the side effects of the vaccine. The caller had gone to her doctor a month after the vaccines, she had both vaccines and started getting electric shocks in both of her legs. The sensation was in between the hip and knees and felt like she was getting electrocuted. The caller went to her rheumatologist and they gave her a Prednisone burst pack. The Rheumatologist explained that sometimes if there was inflammation in the caller's body it will feel like this because of the nerves and the band that hooks her hip to her knee that was where the problem was. The prednisone didn't do anything for the sensation. It feels like the side of the caller's leg feels burnt and she has never had this before. Other people were reporting nerve problems on the TV program which was why the caller's girlfriend thought of her. The caller was wondering if this sensation will go away? It has been two months now. The caller doesn't get the electric shocks anymore but now she has a burning sensation in her legs and it never stops and was worse than the electrical shocks. The caller had never had this problem and then she had the vaccine but the doctors said it couldn't have been from the vaccine. Prednisone- 20mg of prednisone for 7 days.
