hi, I think your husband had a acid reflux..and im sure it is because of his stressful job..because acid reflux can be triggered by stress. It is exactly what I had experience 4 yrs. ago. Right now it was managed.
I think when you stress anything is possible. He may need to be on a daily regimen of antacids. The numbness could be from stress or carpel tunnel possibly. The urinary I'm not sure could be stress related as well. Maybe needs to go have a good once over at the doctor. I wish you all the best.
