Help - abdominal pain that goes away when lying down

I have had a similar problem now for about a year, but I can't pin it on menstrual cycle because I am male. One thing I do have is Diastatis recti - a separation of the abdominal muscles, which is common in pregnancy (but usually resolves once the baby is born) and can also occur in the obese - unfortunately I do fall into that category.  There isn't a whole lot out there on Diastatis Recti, but enough to suggest that this condition could be a cause of my discomfort as it causes the core abdominal muscles to function badly and compensate in ways they weren't meant to work.  I'm going through other tests as well to make sure it isn't anything more serious, but at the moment I am thinking this may be the cause.  Unfortunately surgery is the only cure, and isn't guaranteed.  In the meantime I am trying to lose weight to take the pressure off the muscles and we'll see what that does.

The pain still coming back now and again when my stomach is empty especially during my period. I hate the pain and now that I’m lying down and reading above comments. I realised I have a lot of IBP symptoms during my period but I don’t thing I’m going to take any meds for it apart from “making sure that my stomach never completely empty”. I’d look into natural remedies though for balancing the pH level in my body. 

I have had this same pain for years (like 30!) and the doctors never could figure it out.  Although they liked to say it was IBS.  Usually it would come on slowly and get the pain would get stronger and stronger, until I felt like I might pass out.  Only laying down would make it stop. And it would... immediately!  I think I've narrowed it down to being either chronic Pancreatitis, which can be relieved by laying on your side.  Or, one doctor at Cedars, said she thought I might have a hernia.  Does your stomach get all bloated when it happens?  It does for me.

Wow. So glad I found this this morning. I've been suffering with abdominal pain on and off for about two years. Usually, it starts in the center of my stomach and moves either left or right. It's often accompanied with a drastic change in bowel movements and nausea. Usually, it'll fade after a few days. Today, I was awoken at 3am with a sharp like pain in my stomach as well as gas. After around ten minutes of laying on my back, the pain eased. Instead, it turned into a dull sick-like feeling across my tummy. Now, I only feel okay when I'm laying on my back. I've been to the doctor for the same several times but to no avail.
