I have a persistent thickly cough which I have had for several weeks. This is accompanied by sneezing occasionally and running nose. My mucosa is clear. I have used nasal spray and antihistamines all to no avail. I have also got a hoarse voice but this is probably associated with thyroiditis which I was diagnosed with following scans, and ent investigations. I take fluoxetine 20 mugs daily which I was prescribed six months ago following the death of my son. I am otherwise a fit 69 year old woman but a little overweight weighing 12 st 6 lbs. I am a non smoker and only very occasional drinker.
