2 weeks ago i had a chest infection that brought along a nasty little cough. With the cough came a horrible cold and occasionally i would blow my nose and there was bits of blood in it. Thursday this week i got to work in the morning after walking and had a really bad nose bleed. The infection was two weeks ago and i'm well over that and the cold. However today i was riding, nothing intense just a slow ride at a HR of 120-140. After about 30 mins my nose was blocking up so i went to spit and as i did i thought it looked red, so i did it again and it was really red. I stopped at some toilets soon after to blow my nose and it was pure blood. It was coming out my mouth too i'm really creeped out by this. I have a doctors appointment but not til the end of the week. In the mean time does anyone know what it is exactly that's likely to be bleeding and what's causing it? On saturday i did a ride of about the same intensity for 3 hours and had no problem. In the last week i haven't hit a HR of over 160 as i'm taking it easy after the infection, at 17 with a Max HR of 203 i don't see 160 as being particualrly intense. What do you guys reckon?
