Can grass,mold etc allergies make happen upset stomachs?
allergies to grass and mold can cause excess mucus, which can wreak nausea when it slides down your throat and into your stomach. so my answer is yes.
beauty is within the mind, so why get concerned abot external appearances.
yes most noticeably take benahydryl or something for those allergies and probably your stomach will consistency much better if that is why your stomach is hurting...best point to do is chart what you are doing when the problems start and then try to do away with the cause as much as possible
