Hi I'm happy to join in. I go swimming a couple of times a week for half an hour in a 25m pool , but I don't keep count of the laps (so my body can tell me how much I should swim in that half hour, so I don't overdo it, but also because I always lose count)so does that rule me out?

I mainly do breaststroke because my specialist nurse told me it would help open up my chest wall. I do a lap or two of freestyle/crawl but I have trouble with the breathing because of the reduced lung volume (chest wall expands 1cm cf the normal 5cm for my age). I only know how to do freestyle with a breath on the fourth stroke and have trouble getting enough air in for that long now.

Currently managing my AS with humira, methotrexate, low starch diet and exercises. Also taking omeprazole, metformin etc.
