My 14 year old daughter may have behcets. Has been hospitalized for ulcers. Before the dr knew want she had. But since that time has had a few more ulcers out breaks. Was but on peridsone 50 mg. Now has no ulcers but has headache ever day and stomach ache at least twice a week. She has bad trimmers. Dr have started to take her off peridsone down to 30mg. What I wanted to now is can you have a behcet's flare without the ulcers. And are stomach ache and headaches and trimmers something that happens with behcet or could it be just form the meds.
