Vitamin D and progression

Hello everyone, I am in the process of getting diagnosed and the main contender seems to be sarcoidosis! The rheumatologist I saw recently isn't 100% sold on sarcoidosis because I am white/Native and it has seemingly progressed extremely fast, but pathology and my PCP believe it is. I for sure have granulomas in my right axillary lymphnode that is extremely painful, I have joint muscle and bone pain, night sweats, chills, dry cough, chest pain, light and sound sensitivity, joint stiffness, muscle spasms, a full body rash that comes and goes mainly affecting areas I have tattoos, and a constant headache. Basically I hurt all over and have been taking a ton of otc pain killers and Ketorolac spaced out, but nothing helps. I've had all the labs done for autoimmune disease with them coming back negative. I'm being sent to pulmonary to confirm the diagnosis. The time frame of everything is about 2 months which leads to my question, has anyone with a diagnosis had it progress this fast? Also on my labs my vitamin d level was 13.9 ( highly deficient) is this common in sarcoid? Honestly I don't care whats wrong I just want treatment or relief, because at this point my pain makes me feel like vomiting. If anyone has experienced this or has insight, please let me know! Also I forgot to mention but they have loaded me with corticosteroids, antibiotics, and antihistamines while trying to figure out what is wrong, non of which helped besides knocking me out! Update: I had the ct with contrast done, and my lungs are clear! However, I now have lumps and indentation in my right breast, swollen left axillary lymph node, left half of my chest is swollen, and there's a node in my chest that lacks a fatty hilum. Maybe some kind of cancer? I don't even care at this point, I just want pain relief. I can't breathe properly anymore, but my lungs look and sound clear. My vision had been getting worse, and half the time, all I hear is ringing. I'm 19 f, I should be able to walk around the mall with my sister and nephew without chest pain and shortness of breath.
