Radiotherapy

hello......I hope you are feeling a bit better now you are properly awake. I don't want to sound alarmist but reading your comment my instinct would be to recommend you get a Covid test today if possible just to eliminate it. The symptoms you are describing are definitely two from the list. As your radiotherapy finished two weeks ago and you didn't have the problem before I personally wouldn't dismiss the possibility without checking. Hopefully it's just a summer cough, maybe a reaction to pollen. Do you live in the countryside? Where I live there is a lot of pollen from sunflowers in the air which cause a lot of aggravation. I am having to take antihistamines to keep a cough at bay but it's not a dry cough. 

Sorry not to be more reassuring but in these difficult times.....I think we all have to be vigilant and get everything checked by medical experts.

Take care. Love  Karen
