I have now been told that what was surgically removed from my lung is almost certain to have been TB. Its too late for pathology to test it and I can't now produce sputum so I am on TB treatment. I searched online and accidentally came across tubercular arthritis so I now wonder if my TB predated arthritis. I am waiting to discuss with my rheumatologist whether I should restart methotrexate. Despite my GP supporting this, I am very reluctant to do so, partly because I think I will need all my body's resources to cope with the TB antibiotics, also because I've been off it now for 5 weeks as I stopped because of surgery. I'm wondering, when I had fluid drained from my swollen knee if it should have been tested for TB. I never had the rheumatoid factor so was labelled with inflammatory arthritis.
Although it feels bizarre and very unexpected I am relieved to have a diagnosis and an excellent supportive team to monitor my treatment. As TB, unlike arthritis, can be cured, I count myself as extremely fortunate.
