Diagnosed with GCA barely a month ago, I thought I might be stuck with the cough mentioned in my earlier post also accompanied by nasal congestion. So not wanting to take any more meds I've been using Sterimar Congestion Relief, a nasal spray which is drug free and consists of micro infused sea water! It sounds a bit wacky but I've found that after using it twice a day that my nasal congestion and cough have pretty much gone. It's widely available in chemists shops. Maybe others have tried this product too but I wanted to pass on some good news.
