Frustrated (long)

I'm a side and tummy sleeper. I found no matter what position I sleep in it's uncomfortable. It throbs even more in these positions. When I lay on my back, it's not as bad but, the pain is still there. I feel a lot of pressure, throbbing, like I have a gas bubble just under my left rib. It hurts to walk up right like something is pulling. It also radiates to the back as well. This is exactly what I told the doc and he said "ah, you'll be fine".

I am not a doctor and have no clue obviously, but that does not sound right at all.  Hang in there and get to another doctor asap.
