Belching, nausea & midriff feeling of fullness started immediately post tummy tuck. Now day 11 still very bothersome.

11 days post op Tummy Tuck. Nausea was severe from day 1. I thought it was anesthesia and pain meds and it has improved. Now it's moderate but constant with frequent belching and epigrams trick fullness. I get SOB while talking. I feel awful! I had a small hiatal hernia pre-op with occasional indigestion. If the plication caused this will I need a hiatal hernia repair to resolve these symptoms ? Please tell me I won't have to suffer like this always!!!!
