H-Pylori?

I recently just got diagnosed with Campylobacter due to food poisoning and its impacted my mental health like hell. Tomorrow would be just x3 weeks in total that I’ve had issues. My GP (doctors) did a stool test and found CAMPYLOBACTER, they said it will take time for it to clear up as my immune system should clear it without the need of antibiotics. However after reading other peoples experiences i feel its not best to wait that long and get anti biotic’s to clear it up before it leads to anything serious. At the moment i feel better in general however i still notice my stomach makes more noises in general, my stools are forming quite solidly, no vomiting or diarrhoea. BUT i have noticed a few chest pains more than normal and if i introduce some of the meals or foods i used to eat, then it wont sit well and my stomach will hurt leading up to me going to the bathroom, but after I’ve been toilet then i’m fine again. Any suggestions or advice would be greatly appreciated

My questions are:

How long generally does this take to fully clear from the system if so, Are there any chances this would come back randomly?

Can this leads to any other serious underlying health conditions such as Chrons or IBD?

UPDATE: I’ve recently done a blood test, protein levels, serum C levels and white cell count levels are normal. I did have an appointment with the doctors and as I’m still having sharpe pains in the middle of my chest (sternum) My stools have improved however i find that one day its normal and forming well then the next day its broken into smaller pieces which is still worrying, also sharpe pains under my ribs and the left side of my back still aches at time. I’m not vommiting, i starting to eat more foods at least x2 meals a day, have noticed that I’ve dropped alot of weight and weighing my self each day and numbers seem to be decreasing which is concerning,. The doctor just said it will take time to heal, but im convinced it maybe something more serious that their not taking into account?

I havent done a H-pylori test just yet, but is this something i may have from catching Camplybactor?
