Looking For Information On Clubbing Fingers. Went To Dermatologist Ended

looking for information on clubbing fingers. Went to dermatologist ended up with primary doctor, took a breath test (which had it's technician flaws) and then a CT scan. I was told I have fibrosis. I feel it's more of a heart related issue and not the lungs itself causing the issue. My father had MDS and heart disease, my mother lung cancer and the more I think about it she also had clubbing and finger issues. My fingers also crack and peal and I have had a difficult time clearing that up. I have many concerns and feel my doctor just blamed it on smoking and no further instruction really. I'm not a wait and see person, I would like more answers or a place to look for info. I also have PTSD and am on sertraline and at one time risperdal. I have read where that combination can cause drug induced fibrosis. any thoughts or direction. I am feeling I need a new doctor's opinion. Also last week my sister informed me that she has hereditary hemochromotosis ... (too much iron) ... and if that has anything to do with my lungs. she was JUST diagnosed a few weeks ago. thanks -N
