DH has had slight stomach since Saturday morning ( he had a cheapish pizza Friday night which we think caused it). Has had diarhoea intermittantly aswell. Last night cramps seemed to ramp up a notch and now he's on lots of pain and struggling to go to work normally I'd advise him to stay home and take it easy but s recent situation at work not involving him means that today it's not an option. Is there any over the counter medication he can take to help relieve some of the pain? If it gets any worse I think we will have to head to a walk in clinic
