This is my first post here. I was hoping someone may be able to help, or have had similar symptoms before.
A year ago (september 2014) I suddenly had very bad bloating and distension. I hadn't put on any weight, I was exercising every day (it became a new hobby!) and eating healthily. I've always been very slim, and from my exercise regimen I had become very toned. Suddenly one day I looked down and realised my stomach had ballooned. I measured myself and had gained 4-5 inches. In January this year I started getting pelvic pain - to the extent that I couldn't walk some days and would have to have time off sick.
Since then, I've had a cystoscopy to test for interstitial cystitis (I don't really have any other symptoms though), and a laparoscopy to test for endometriosis (again, no other symptoms - in fact my cycle is light and sometimes pain free) - both came back clear. I've also had numerous blood tests, and the only thing they found was that I had B12 deficiency again (I had it in 2013 too). The treatment didn't affect the bloating or pain. I've also had ultrasounds over my pelvic, kidneys, entire abdomen etc and nothing. In 4 weeks I'm being sent for a colonoscopy to check for Crohns disease and other possibilities - I'm sometimes constipated, but even when I'm regular the bloating is the same so I don't believe it to be IBS (I've had the issues even when my diet was at its most bland/strict). I've only had diarrhoea once in the past 5+ years (and that was from eating foreign foods a few months ago, after this problem started).
I've been able to keep the pain under control by following a low acid and gluten free diet (I'm not sure if gluten free helps as now occasionally I eat it and all that happens is I feel a bit fuller, but it was recommended to me).
The bloating is constant - it never gives up or stops, not even for a day, or an hour. It's also the same in the morning as it is in the evening, even before I've eaten anything. It starts from the lowest part of my abdomen/pelvis and stops just under my ribcage.
Has anyone heard of this before/have any ideas of what it could be? I'm at my wits end, I'm in my early 20s and have lost all my confidence. I've started exercising again - I originally had to stop because the pain was so bad. Nothing I do seems to ease it and I'm desperate.
