Hello, I am 32, female, I had a lump on my neck limph node and was diagnosed with latent tb. I completed the 6 months treatment and final x-Rays showed little scarring. Now, 8 months later, had a stabbing pain on chest, a new x-Ray showed more scarring than before. Have an MRI scan booked. Is this still tb related? What else could cause the scarring? Thank you.
