I have sarcoid and have blood drawn regularly.  The last time, about 8 weeks ago, I developed a lump at the site that felt like a marble.  The area around it is red and blue.  Last week I developed another on my other are.  It has been several months since I had blood drawn from that one.  What is going on?
HI, Welcome to Chat Doctor with your query. Based on the facts of your query, I would suggest you to consult a Physician rather than self-decided aspirations of blood from such lumps. As Acidosis is autoimmune disease with lungs inflicted in 90 % patients, possibility of lung affection in time to come is challenge which you should be worried about. Skin lumps currently indicate, that the autoimmune attacks are recurring and active after 8 weeks again. And you have to be on watch with your doctor. You need to be very careful with your bland and well-balanced diet, which mostly is the exacerbating factor known in such cases like autoimmune diseases. I would hence suggest being under guidance of your Physician and be with needful medicines to control the remissions periods with these medicines like Steroids with It D3 supplements. Hope this would help you to plan treatment with your doctor. Will appreciate your review write up and hitting thanks, to help needy patient visitors like you at Chat Doctor.
