Thank you for posting your question here, I will try to answer it to the best of my abilities.Dolonex
, would have been my obvious suspect as it is known to cause acidity in the stomach and even lead to ulcers when extensively used, but since your doctor prescribed you with Pan (a drug which counters the effect of dolonex on your stomach), your wife shouldnt be having these problems.
Has your wife had gastritis
in the past or was she taking any medication for her thumb before this?
Okay coming to your last question, none of the medications prescribed to your wife interfere with her periods, as such it is entirely possible that she is pregnant and that she is feeling all this discomfort because of that. I recommend you either have a home pregnancy
test done or go to a doctor and have him test your wife's blood for the signs of pregnancy.
I hope this answered your question.
