After
mountain biking in the countryside I get a sore throat, I can taste metallic or blood in the mouth, but there is no blood there.
I don't get this walking, even walking up a mountain, just cycling.
When on the bike my nose starts running especially now during winter, when sat at home, it feels like mucus going to my lungs making me have chesty cough.
I told the doctor about it two years ago, I told them I feel faint after going up hill.
