Could My Untreated Rheumatoid Arthritis Be Causing Rapid Hair Loss With Bald Spots, Recurring Vaginal Infections, And Widespread Body Pain?

I m a 23 year old female,I was officially diagnosed with rheumatoid arthritis when I was 16 but I had had symptoms from childhood.When I was younger I was mostly unable to look down without leaning forward because of an intense pain in my tailbone for a couple of hours in the morning.My question though is about the rest of my body,Ive tried all hair remedies but my hair keeps falling out and now I have a bald spot in the back of my hair that just started out as a smooth tiny dot,now it measures 5cm wide (it s almost a perfect circle)It took only a few weeks to get this way and my hair does not recover.Note the skin there is as smooth as ceramic ,no hair follicles nothing,it s like hair never grew there.It doesn t itch or hurt or burn,it s just spreading.Could it be a result of my arthritis.And could arthritis have given me 4 years of recurring vaginal candida (twice a mnth) when I was a teen? And BV for a while after..and bad facial skin that scars and never heals always I m not on any medications,I cannot afford it.Its troubled me for years,I feel very old.I appreciate your response you have no idea how much I need proper medical advice.I have tested for HIV/AIDS and sti/std s and come out clean.My entire body always hurts
