do you also have swollen lymph nodes in your neck and down by the collar bone?
not shot related (i never got it) but in 2020 I had night sweats and a low grade fever (often), itchy dry skin and swollen glands in my neck. it turned out to be hodgkins lymphoma. (Thankfully i am doing extremely well with treatment.) I just wanted to share, not to get you nervous or anything, but with cancers time of discovery is of the essence.
