I'm really concerned about my health and could use some advice. Over the past 10 months, I've been having issues with sticky sputum and left side chest pain. And just recently, I noticed blood in my sputum along with pain under my armpit. I've lost around 12 kgs too, which is worrying me even more. I've done quite a few tests, like a CT scan, a heart echo test, and even a sputum AFB and Mantoux test, but they all came back normal. I also checked with a CT thorax with contrast and had a couple of chest X-rays, all normal. Blood tests like sugar, urea, creatinine, CBC, and a seroconversion test were negative too. I'm not sure what's going on, and I'm really anxious about it all. Can you help me figure out what might be happening or suggest what I should do next?
