My Husband Has Been Suffering From A Constant Cough. He

My Husband has been suffering from a constant cough. He has been to his primary who said his cough is due to acid reflux. He has had chest X-rays which they want to repeat. Gave home antibiotics, cough medicine with codeine as well as mucin ex to take. This has been going on for more than six months and he still has no relief. He is tired and is not sleeping well. What is your advice going forward as his co pays are high and his primary really has not addressed the issue. Not going to pay for advice, please delete me from any pr to my email address. What a scam!
