Hi @Dooby
Can I suggest you get in to see an allergist/dermatologist to find out what you are allergic too exactly. I discovered (almost by accident) that I was anaphylactic to colophony - which is a natural occurring gum/resin (it's a sap) but is generally used extensively in sticking plasters/bandaids and in surgical glues. What this did mean was I was tested out for what dressings I could have (in my case none of the surgical glues but some of the dressings - op site and comfeel being a bit bonus for me along with mepitel film). I'm telling you this as I've been "allergic" (ie had the skin reactions) to dressings for years without knowing it could be so much more but knowing what dressings I can have has made my double mastectomy (and chemo and radio) do-able.
Good lucj
