I've had re flux for many years, past 2 months its been so bad that I have vomited. past month I had congestion with cough very bad, hard to breath. Urgent care put me on steroids for 5 days and antibiotics for 10 days. I finished the course of meds. my cough is still bad with congestion,my ribs are very painful when i touch them on the sides and under my breast. I noticed there apears to be a lump where my sternum is very tender to the touch. Im very frighten that ive been miss dignosed and it may be cancer. please tell me what should i do?
