[|Human|] I have a 2 to 3 inch knot on my back left midway rib cage. I ve had it for 6 months or longer. Recently that area has started hurting in a terrible way and I m feeling short of breath. The pain has been constant for the last 20 hours. I m scared and I don t have insurance
[|AI|]  Thanks for your question on Chat Doctor. I can understand your situation and problem. In my opinion you should first consult pulmonologist and get done1. Chest x ray2. Ultrasound examination of local rib not.3. CT thorax if required. Rib swelling and breathlessness is seen in1. Rib fracture2. Rib cancer or lung cancer with rib metastasis. So above-mentioned investigations are required to diagnose your problem. So first diagnose yourself and then start appropriate treatment.
