Hi thanks for contacting HCM.... Here you have diagnosed with asthma.... During asthma attack you might have infection and so stomach pain can be there as associated viral flu... First confirm your diagnosis... Consult good pulmonologist and investigate with pulmonary function test by spirometry... If repeated attack there maintainance dose inhaler with foracort started....containing formeterol and budesonide... Avoid exposure to dust , pollen , pollutants to minimum.... Take one tsp ginger juice with honey daily to sooth respi tract.... Raw ginger with salt also useful.... Garlic also good one..... And yes try to avoid stress as it can precipitate attack.... Take care.... Keeping these in mind you can visit doc. Take care
