Wind Pains

Patient: Wind- Please could you help, i have suffered from wind pains for approx 8mths, i was prescribed gastroentiritis tablets which worked for a while but then over the last wk i have suffered 4 seperate days. It starts as an ache in the stomach always in the afternoon which then leads to severe stomach pains which leave me doubled over in pain, all the while breaking wind constantly, tonight for example the ache started at 6pm, severe pain by 8.30pm and then pain free by 9.15pm, but i am still breaking wind at 10pm, this is getting me really down, i have tried to look at what foods i consume and can not find a link as i eat varied foods and it never seems to be the same food i’ve eaten when this occurs. Could you please advise what the cause of this is.
