Sibo, ibs due to antibiotics and typhoid

So I basically had typhoid(fever, abdominal pain) which was unfortunately diagnosed after 1 month. So after that immediately a huge dose of antibiotics was given to me , my abdominal pain went little bit down , my stool was also okish. Because I was taking few probiotics like bifilac capsules. But after sometime I felt dizziness. So I left antibiotics but dizziness didn't went and even my flanks started hurting did a kidney and liver test everything was fine. But after that dizziness didn't went and gas,bloating, constipation with diarrhea is constant. One of my medical College friend told me it could be either S.I.B.O or IBS. Then I researched on sibo and IBS and I'm suspecting sibo as antibiotics killed my good bacteria too and acid reflux medicines decreased my digestive enzymes. That could be the reason the bacteria of large colon could have come to my small intestine. Because chances of IBS is very low as I took probiotics. Still I'm not sure of anything please help me.
