Hi, i am 52, 135 lbs in very good condition. a month ago I had a very upset stomach with a fullness feeling under my left rib for a week, feeling tired with a feeling of nausea but no diarrhea. It somewhat went away then i began getting headache and congestion which also had a low grade fever and it went away after 5 days. Now it is 2 weeks later and it's happening again. My husband also has a repeat of the chest congestion 2 weeks apart. I assumed this was viral so have treated it with Zicam, herbal tea, ibuprohen. Now I'm not sure what it is. Also a note- we are remodeling our home and recently had alot of concrete dust in house. Any ideas?
