You know what, I have been having this problem lately, and I am the only one in my family that has been. I am the one who wanted, bought, and care for my chickens. I recently found out the reason why. Is it possible that your hubby is having problems with his gallbladder? That is the culprit with me.
Mine, wierdly enough, was contributed to by a reduced fat diet that I was on for several years and quit suddenly. We eat relatively healthy almost all the time, but earlier this summer, we got so busy that we were doing the whole stop twice a week for take out or quick fix meals at home because meal planning went to to wayside. When my chickens started laying well, we started eating breakfast for dinner quite a bit. About two weeks ago, we made fried deer tenderloin, mashed potatoes, mac n cheese, and GRAVY. After the gravy, I had a full-blown gall bladder attack that lasted for several days. My friend the Doc said that it was because my body had not had a lot of fat for so long, and then all of a sudden it was overloaded. I have been more careful since then, and my symptoms are improving. I am looking for herbal remedies to help with this, and am going to try to manage it. I had eggs at lunch today with no ill effects.
Oh, the symptoms i experienced, just in case you want to compare, were nausea, increased hiccupping, acid taste after eating (never done that one before), increased gassiness, and the worst one (the one that made me call my friend) severe pain behind the right shoulder blade that was not relieved by anything. I woke up in the middle of the night with this pain, and at first, thought I was having a heart attack. I seriously had to consider what side of the body your heart is on, because the pain was so intense that I just couldn't think straight.
