hi, I have had crohns for just a bit over a year now, with many flare ups which i am used to, however recently it has felt different to the other times i am back on budesionide 9mg which normally helps but hasn't seem to, my symptoms are feeling really sick and cramping,back pain as well as dry heaving (new to me) however i will go for 2-3 days and feel OK then feel really unwell for 1-2days then the whole cycle begins!!!, my question is, is dry heaving normal for people with crohns or is it just me? also why do i get this and is there anything i can prevent it?. It all started when I went to Egypt and got a stomach bug as well as my friends swell although theres lasted 4 days and mine never went away it seems and got worse when my doctor started to think it was now a crohns flare u. hopefully someone has been in the same boat and has some advice please!!thanks
