Hi Misssy2, yes I have had the hiatus hernia, which is basically the valve in the oesphegos(?) not closing and is faulty and causes reflux, for several years. Doc said at time of diagnosis it's not something you fix as it's is very tricky. But it can be managed quite easily. So it's not the hernia. I have no obstruction in my breathing just very hard to breathe in and out. If I take a deep breath my chest kind of locks and my chest shudders on exhaling. No mucous but have a very irritating cough.
I'm not sure what a hiatus hernia is...but I vaugley remember that any type of hernia requires treatment. Is it possible that your hernia could be causing these symptoms? I googled the symptoms and although they are not a direct match, everyone is different. The hernia could be pressing on your diaphragm causing your breathing problems. I would check into that with the Dr.
