She experienced itching in her head, neck and around her shoulder, she has psoriasis in her scalp and her neck on 31Mar2021, the psoriasis has flared up she didn't have a rash or itching anywhere else and it didn't itch all the time, she would like to know if the itching in the areas where she has psoriasis could be related to the Pfizer-BioNtech Covid-19 vaccine, she stated that she has diabetes, high blood pressure and high cholesterol, sometimes when her blood sugar levels were high it makes her skin itch and she hadn't checked her blood sugar levels this morning, she mentioned that this could relate to diabetic neuropathy because it deals with nerves. She also experienced other side effects; body, muscle and joint aches, pain in arm where she was given the shot and she had the same feeling in the other arm. The patient stated, she got my second pfizer vaccine yesterday and she started itching on head, on her scalp and her neck while she was trying to sleep, she just did not have any Benadryl or anything like that so she just scratched and finely it went away but she noticed that the side effects included rash but she didn't have rash all over her body, she was just having itching on her head and on her neck and she also have psoriasis on her neck and some on her head so she started wondering was this a severe allergic reaction or was this something will go away because she was not feeling much right now and sometimes her Psoriasis did this, it itches quite a bit and then it goes away, so she called your number just to make sure, its not an emergency or anything, she just called to make sure that she should be okay because she have been reading something that people who get terrible allergic itch reaction they had to go to the hospital and their skin was really messed up and she didn't think thats her situation. The patient stated that she did not have anything for itching so she just scratch and hopefully it will go away, it was not extreme, but like she said she had Psoriasis, on the bottom of her, on her neck, you know down below her neck, below the hairline, she had Psoriasis, and that aggravated her Psoriasis, thats might be why it itching. She did not feel like getting up and taking Tylenol, it was just miserable but as soon as she woke up this morning she took 2 Tylenols and she was feeling better already and surely she thought that was only other side effect that she had, she didn't have fever or anything like that. Outcome of the events Itching in her head, neck and around her shoulder/itching on head, on my scalp and my neck was not recovered and for all other events, it was unknown.
