Sulphur. I swear by it. I have asthma and when I get a chest infection it can linger for weeks and weeks, even after a course of antibiotics. Sulphur tablets from the chemist or a health food store will break up the congestion and get the infection moving. For me, it is the ONLY thing that will clear my chest.
Obviously I am not a doctor, and maybe a trip to your GP would be best - but I would highly recommend you take Sulphur in conjunction with whatever the doctor prescribes. I always have it in the house.
Get well soon
