cough with burning mouth and rash

lve had a chesty cough for at least 6 months now and have recently developed burning mouth and tongue and a burning itchy rash on my chest and cramping in calf muscles in bed at night, are these connected and do you know what could be going on? lm soooo sick of it! tired and generally unwell too :(

These are broad general symptoms that related to different areas of your body.  Because this has been going on for so long and involves your chest, as well as your muscles, it might be a good idea to have a physician perform a good physical examination to see what is happening and get a better idea of whether these are related or unrelated symptoms.
