I know this isnt really related to emet but I just thought I'd get some opinions as I know if this case worsens it could mean serious abdomen stuff...

So I went to bed very relaxed last night at around 12:30am and woke at 2:30 to severe pain surrounding my belly button area. I had zero n* or D* or anything like that, it felt like I had pulled a sensitive muscle. Sad thing is , I remember having this pain from the age of 11...its sporadic and sly as it can be agony for a few seconds and I'm unable to stand however with certain positioning it eases. I took an ant acid after half an hour of the pain last night and told myself to stay calm. My bellybutton looked clean, fine, healthy etc and my upper stomach felt perfect but this pain was literally as if I had a stitch in the centre of my tummy. It occurs every 5-6 months and is usually when I'm mid-sleep. I winded myself in the chest yesterday after having an anxious chat with my mum cos I stood up too fast and I was a bit on edge after we had a little fight(ironically over my anxiety). I get very anxious a week before my period and was wondering if this increased the chance of trapped wind or anything ...mum said its most likely that as it vanished one hour after but I don't think trapped wind can be THAT severe for one hour right? Anyone ever had this?
