Covid 19 Positive. Cough Medicine?

[gordiescotland1]

Hi there.
Last night I went to bed with a sore throat and a cough. Got up this morning feeling a lot worse. I took a lateral flow test to my horror I saw 2 red lines as clear as anything. So i am now isolating until i get 2 days of negative. Feeling pretty rough all my joints are aching, I have no appetite at all so I must really be ill. But worst Is this cough. Dry cough really tight chest. I want someone to go to the chemist for me and get cough medicine but I have had problems in the past with a fast heart rate with some of them. I have Atrial fibrillation under control most of the time i would like to keep it that way. Any ideas anything safe?
I went to mum and dad for dinner last night when I woke up yesterday morning I told my mother I had a sore throat and she said I was being neurotic, not unusual!! She said she had one but it went away. I tested before I went and it was negative.
Anyway they think I got it on Wednesday night I went to the pub to watch the Rangers game with a friend it was quite crowded. Mum thinks I got it there. But there is no way she can prove it. I was on the bus the other day and a woman was coughing behind me I kept on turning round and giving her dirty looks. I cant believe I have managed to avoid it for 2 years and got it now

I think you are getting over this
wait four weeks and make sure you get a second booster

I don't feel the need for any medication to relieve my cough. The best remedy is always a natural one. I've had Covid before; it was a decent one this time around. My throat was really hurting, and what helped me was oregano tea with a spoon of Manuka honey in the morning. I wanted to share my favorite brand, which is Amazon.com User Recommendation?ref_=ast_sto_dp&th=1&psc=1 it's always pleasant to get a product with positive evaluations rather than anything online.
