hi sarah..no allergy test as of yet...and yes i have had an increase in stomach problems..we call it the GI flu in the medical field...abdomen swells up, sounds like july 4th with the gas rolling around in it...and painful for about a day, then horrible lower abdomen cramping with diarhhea that lasts till i just about fall out then everything gets better after about 3 days...i have had colonscopies and egds that are normal except for a hiatal hernia...my GI says i am lactose intolerant, based in cutting it out of my diet...this also tends to happen after ingesting almost any kind of medication(claritin, zrytec, allergra, any antibiotics except keflex, but phenergan makes it better), also stress induces a bout with it..also one glass of wine will give me a horrendous headache that last three days...i take bendryl a lot...the abdomen symtoms are what started first and then the other symtoms later...thanks for your help..
