Suggest Treatment For Severe Bloating And Bulging In Navel Area

i am having severe bloating and what appears to me to be an umbilical hernia...could the two be related? the doctor just by a phsyical exam indicated probably not but I have two small coin sized bulges in my belly button and bloating pain and burning about two inches above navel really the whole abdomen area down to the pelvic area..I was recently checked for ovarian cancern with negative results via ultra sound I am not obese I might be 20 pounds overweight but I have had much strain in working out giving birth and having surgery where going to the bathroom afterward nearly had me pass out and taken to emergency to extract...lots of hours of straining...sooooooo I have a hard time believing that all my symptoms dont point to a hernia even though I was told likely not and scheduled reluctantly for a cat scan which I don t want due to the radiation I have had in my life...I want to know too if there are ultrasounds that can determine the same thing...I have read about dynamic ultrasounds...but cannot seem to find anyone locally to do one...
