Eczema Treatment Care

My grandmother passed away in 2001, primarily due to Lupus. I’ve been worried that I may have/get Lupus (since it is a genetically transmitted disease). I have common flare ups of a rash that i thought was eczema, but recently have thought could be related to Lupus. Could Lupus cause Eczema? Are they linked somehow?
Thanks!

I have eczema opposite my elbows and now it’s also forming on my wrist. I REALLY HATE THE ONE ON MY WRIST!! Coz everyone notices it and they think it’s disgusting and there is no way to hide it. I don’t know what caused the eczema but anyway it wasn’t there till last year. I am worried it might spread to other parts of my body (like how the one on my wrist formed) and it’ll form in obvious places like my hands – when i shake hands with someone. Please help me and if you have anything that can help improve the eczema please tell me!! <3
