Hi Lori,
Yes, I had JAK test and negative. I think they ordered more tests that are not back yet as take more time. I do have an enlarged proximal phanangeal right ring finger joint and sternoclavical joint with no pain but deformed bone but never really determined cause but I have not had injuries or falls to cause them. I did have hand MRI saying to rule out inflammation/infection which was never done. I have negative rheumatoid factor from lab and no psoriasis. I might be able to get a new hand MRI to compare but Hydrea and aspirin is recommended for life now. Hand specialist I saw for first issue in 2023 was pretty useless and did know what I have from the MRI and wanted to do exploratory surgery which I declined. Difficult to get second opinion and rheumatologist did not know what it is either. Mostly frustrated appointments with docs I must say.
