Hi, when i exercise, whether it be horse riding or going to the gym, and sometimes even when i walk fast i get a pain as if chlorine was going up my nose and behind my eyes, it stings and is painful, somtimes i get a headache behind my eyes and back of my head following the chlorine feeling, normally it doesnt last long maybe 5 to 10 minutes but today after horse riding it is still there after about 2 hours, i try to stop what im doing and have drink some water when it happens but today i couldnt as i was riding, i dont know if this is why its taking a lot longer to go away, any advice would be much appreciated as it was really painful today and starting to worry me a bit.
thank you
