I have systemic scleroderma, Parkinson s, PAH, ILD, GERD, FIBRO, CHRONIC MIGRAINES, SOJGRENS, CHF - 1 episode, and a few other things. Currently I am suffering from severe coughing, weakness, fluid pretension and shortness of breath. Am I having a heart problem (CHF)? Should I call my cardiologist or lung doctor? When I cough it is so hard sometimes that I can t stop it. It feels like it is getting worse. I guess I just need to know which doctor. Sorry to over-inform you. Thank you for any assistance you can give me.
