Hi - I used to run every day....outdoors in the cold even. As long as it was above 20 degrees, I would bundle up in the morning and run in the dark and watch the daylight arrive. I've run 4 half marathons...all in my 30s. I was diagnosed with fibro at 37 and no, I can't run outside anymore. It hurts my entire body. I can't let the cold air hit my neck because then I will have neck pain all day. But I've adjusted. I joined a gym instead and I do the eliptical, or the bike, or lift weights. I've recently started running on a treadmill....only a mile or 2. I will never run a marathon again, or even run the usual 5 miles that I used to do. Yes, it bothers me, but what can you do? I've learned to accept it. I am not bedridden and am grateful to God for that.
