I am so glad you are finally getting relief.
I find it weird you're allergic to hydrocortisone, but that brings me to the next point.
It's becoming more well known COVID causes MAST CELL ACTIVATION (I suspect vaccines may do that too) which makes people have allergic reactions to all sorts of things.
"In mast cell activation syndrome, excessive amounts of inflammatory mediators are released in response to triggers such as foods, fragrances, stress, exercise, medications or temperature changes."
There are facebook groups of people having your exact symptoms.
That quotation above came from the clickable link at bottom of page. A pre-covid article from 2019) on "Mast Cells and Sensory Nerves Contribute to Neurogenic Inflammation and Pruritus in Chronic Skin Inflammation" It's like a vicious cycle.
A newer article on Mast cell activation syndrome from long Covid. https://pubmed.ncbi.nlm.nih.gov/35938771/
Very few doctors know how to treat mast cell activation, even the allergists.
I have to think if Covid can cause this, so can the vaccines because they are similar to the disease itself.
