I found a hard lump in my back. It's on my right side,- right by bottom of my ribs. I have had 2 doctors feel it, & they say its my ribs. I KNOW it's not a rib. its hard & round & it's gotten bigger. I am starting to have a panic attack just writing this. Please help me. I am 31, turning 32 next week. I do smoke, but had an x-ray of my lung area when I first found it in February, & was told they saw nothing.
