Oxygen use for cluster headache

[Aziz]

Has anyone experienced any side effect of inhaling pure oxygen to abort cluster headache attacks. I have been using oxygen for 2 months to abort my cluster headache attacks , maximum for 20 minutes in a go and it kind of always aborted my attacks but then I started feeling a kind of breathing issue which went away when I stopped using oxygen. 

 Does oxygen use affect lungs ?

.....30+ yrs here...hundreds of tanks used and thousands of hits aborted....and the ONLY negative was an occasional dry nose...
