Painful and itchy rash on neck and scalp could be psoriasis or eczema. Psoriatic arthritis can sometimes be alongside RA. Show your specialist any skin issues.
And ask about any supplements before taking them with your meds bc they might interfere with them.

T-sal may help calm your scalp. It kinda smells like coal tar but the scent doesn't linger or stay. Oils won't help your scalp but your lower hair could benefit from certain oils. Don't scratch your dry scalp or skin, be kind to it. As we age, dry skin happens bc our skin thins. Oil and sweat glands don't operate as well. Our immune system can affect those too, causing inflammation, blockages or clogging. I was told to use baby wash and a vinegar/water rinse. But you can research natural remedies and find some helpful things on-line.

Since I have been on a biologic for RA, a burning rash between a few fingers that I haven't had in 50 years is back with a venegance. I've had to remove all my gold rings I've worn for decades. If I don't this rash gets angrier, blisters and oozes. Very attractive. I did have terrible eczema everywhere as a small child which eventually limited itself to my hands, then disappeared until now.
I also am developing fungal infections on my skin I've never, ever had before until biologics entered my life. I have no doubts that autoimmune conditions and the drugs that treat them provoke skin problems.

Its not important. Its also not that funny. But to give my skin a break..i take a shower every other day or every third day. Especially in winter. It helps me.

Paula, I am going to have my daughter try this. She has autoimmune progesterone dermititis. She is so miserable. It's all over her whole body. I wished I would have known this when I had Granuloma Annulare. Thank you for that information.

I use downy sensations & 2 lg bounce sheets, it helps me sometimes I'd like to bathe in that silicone stuff a salon uses on hands. Don't recall, not silicone, idk🤦‍♀️🤷‍♀️
