Here's the situation:
Working on bike in 3 car garage. Propane heater going at my feet. Degreasing and relubing Chain. Cleaning bike with WD40. Hooking up a new computer. Putting new hand grips on, I start to double over from some sort of abdominal pain combined with lower back pain.
I am wondering if it was from a combination of Propane fumes and chemicals?
I have worked many of hours in the garage with this heater, no effects.
Waiting for the Doc to call now. Still have lower back pain, seems like two lower muscles.
Won't be doing that any time soon. whew!
