Diverticulosis reacting after surgery ?

 Hi guys

I'm new here.  I'm 16 days out.  I'm still on my liquid diet because I had a hiatus hernia repaired.  I have been having pain in my right lower abdomen since long time ago supposely produced by diverticulitis.  
The pain has come back since yesterday.  I have been having a bit of probems to go to the toilet since the first week, I have tryed Benefiber (one small spoon a day) with no real result.  I toke once 2 exlax chocolate which made me have craps although it worked.  
Is this pain due to the low fiber diet, should I to expect to have this problem for ever now that I'm sleeved and my diet will be mostly protein?  What do you do (the ones with diverticulitis) with this situation?
Thanks for the answers

Hey,my mom got sleeved in august and me last august,shes been having problems going to the washroom but was told no problem taking senekot or ducolax,what seems to help her is prune juice,kiwis and benefiber,and when shes constipated alot then the pills,
For me im okay with colace and kiwi,
Not sure if uraware there is a monthly support group for people who had bariatric syrgery,so helpful and u can talk and share expierences,its in ville st laurent,let me know if u want more info the next one is nov 17 from 7-9pm,

Thank a lot for all the informations Amanda.  

I will try prune juice and get some senekot, if I can crush the pill I can take it, I'm not allowed to take pills because of the hiatus hernia repaired.
