I'm a 22 year old male and I've live and worked on a farm all my life. About 10 months ago I started raising and breading pigeons (sort of bizarre I know) The barn is well ventilated and we have made sure to wear masks while we are in the barn (over the past 6 months).

My problem has occurred about 5-6 times in the last 10 months and it seems that it only happens after I've been in the barn for a long period of time or if I run in the barn for 5 minutes without a mask.

My problem consist of me waking up in the middle of the night freezing cold (which is strange because I often complain about being to hot at night) I feel sick to my stomach and alot of my joints hurt (mainly my knees) and I feel very weak. By morning I start to warm up and my joins and stomach are feeling better by noon.


I think this problem is related to working in the pigeon barn, but what could it be? Could I be allergic to something in the barn? Should I buy I high quality mask? (every one else in the barn uses the same masks and know one ever has problems like I do)

Any worlds of advice would be greatly appreciated.
