Can an expert figure out this H Pylori puzzle???!

[Ltb]

Hi
Im wondering if anyone on here can figure this out because it really doesn't make any sense to me at all. These are chronological events but things just don't add up:-

1. In July 13 my mum visited both myself and brother in London. She was very ill at the time and had continuous burping/indigestion/diarreah (yellow stool). We all thought it was just a bug. However burping/ indigestion continued from July to October and she was free from symptoms by end of October after taking lots of probiotics.

2. Towards end of July I started having chronic acid burps, even after drinking water. This continued into August. went to doctor who gave me Lanzoprazole. All this did was remove acid but burping and pale yellow stool remained.

3. In August my brother also start having exactly the same symptoms-burping , indigestion and cold burning in stomach.

4. Throughout September and october my brother and I battled acid burping, pains in stomach, yellow stool, sore tongue/mouth, post nasal drip, and self treated with Gaviscon.

5. From July to today (January 13th) Ive had only had Lanzoprazole from Sept 1st to October 1st, and for another 2 weeks at end of October

6. My brother and I had stool test and both came back NEGATIVE for H pylori in October. Mum had biopsy from endoscopy NEGATIVE for h Pylori.

7. I had Endoscopy on 6th January(last week) and doctor discovered Duodenal Ulcer and gastritis and said I MUST have H pylori. Ive taken Triple therapy all this week but am still burping on my last day of treatment.

8. My brother and mum now have the same triple therapy drugs after begging their doctors to have them. Because they both had previously had negative tests Doc did not want to hand out pills. Symptoms are exactly the same though so If i have Hpylori it makes sense they do.

MY QUESTIONS:

How can it be possible that I have an ulcer In January? Considering I took Lanzoprazole throughout October this should've healed the ulcer. Can an Ulcer grow quickly in 2 months?

My acidity levels began to get easier. in July and August every burp was painful acid. By November/ December the acidity was less even though i was still burping. This doesn't tie in with the Ulcer occurring?

My mum seemed to cure herself after 3-4 months. Indigestion vanished, but she wants to take triple therapy to be certain. Is it possible for symptoms to go/die down?

The coincidences are so odd. All tested. All negative in October. I get ulcer so positive diagnosis. Doctor is 100% sure its h pylori. All on same triple therapy treatment yet feeling no better on last day of treatment (brother and myself). Surely the chances of all 3 of us testing negative is very low. I thought the tests were pretty accurate? Also the chances of us all not responding to triple therapy must also be low but this appears to be the case.

Sorry for the long post and its probably a headache to read but none of this makes sense to me!
