That would be great! My question and problem is this
As far as ADVIL is concerned it is non steroidal ant inflammatory Chat Doctor.  The basic problem here in your case is fever and subacute intestinal obstruction. If you're passing flatus with feces then continue with the soft diet along with the antibiotics and sure you can take ADVIL too. If u haven't passed stools and flatus for more than 24 hours and if it accompanies abdominal distension then quickly consult your doctor so that proper workup can be done in time.  Regards
