cluster headaches and exercise in Research & Scientific News Posted March 11, 2015 Ran a mile and a half at the gym yesterday after work. Felt great but still got hit at 1 am with a kip 3 lasted about 20 minutes was back in bed by 145 and slept all night with my cpap machine on ......just wished the beast would go away and leave me alone. ...when I was a kid 16 I was chronic those were rough. ...lasted about 4 years then when I was like 29 they dissappeared for about 10 years ....think the stress of divorce brought them back on cause I have been seasonal since 2010. Mm work for me but we have not seen any growth yet around here. ...just trying to buy time till it gets humid......ugh!
