i don't have any of these things but i do have one persistent thing, some sort of cyst on the front of my calf which sometimes gets quite itchy but mostly is nothing, firstly, and a second related skin issue that has only appeared quite recently, in association with kidney/diabetes type symptoms, where some parts of my skin, especially ears and scalp, seem to get some kind of translucent crust like a scab but not a scab, and when i scratch it off, sometimes it actually breaks the skin and i have an actual scab at that point
best i can estimate is it may have something to do with zinc deficiency, and for which reason i have started experimenting with eating a lot of seafood, shellfish, mussels, oysters, crab, cod, and have had a noticable and quite dramatic response from my digestive system from this new diet input
one of the things i've figured out is that much of the terestrial types of foods, especially meats, here in the EUSSR, are contaminated and produced with feeds and medicines that lead to some kind of health issues being caused by these foods, and i realised that since i live on an island in the middle of the atlantic, probably a lot of the fish and seafood supply is very clean due to the great distance from heavy industry... seems to be working out so far but it will take time to really manifest and i am unfamiliar with this diet choice so getting the stuff that is really good may take me some time to figure out
but this stuff you talk about makes me think about the several issues i have with my skin at the moment, maybe this can help others if you have advice about it
