Hello, my dad has been diagnosed with polymyositis and as an affect of the medicines he has been taking his lungs have been damaged with scarring (pulmonary fibrosis) and has a terrible cough. He has tried some corticosteriod drip but only had it once and suffered very bad backache as a result. His consultant says he must take it what can he do as he is having side effects. Also, does anyone know whether taking alcohol can make the condition worse? Any advice on how individuals cope would be appreciated.
