Ongoing nausea, mucus stools after trip to Cuba

Hello - 
I went to Cuba in March of this year and became ill after a few days I don’t know if it was something I ate or what but I awoke in the night with severe nausea but managed not to vomit which I think was a bad mistake. I was very constipated and couldn’t clear my system (I suffer from hypothyroidism) anyway the nausea and lightheadness continued for the remaining 4 days of the trip and I was unable to eat -just water a couple of bananas and eggs.
On returning to the UK things didn’t improve I felt very wobbly no appetiete, generally unwell and of course weight loss. The stools I did pass were covered in mucus and at one point I was passing straight mucus. Finally I went to the GP and was given 2 lots of antibiotics and then one month of proton pumps. After this I began to feel better and for 10 weeks was fine.

9 weeks ago all the symptoms came back and the GP started treating me for gastritis and I had more proton pumps and a test for h.pylori which was negative (but as I was on the ppi could this be a false negative?) but was given triple therapy anyway while waiting for stool test results which he felt sure would be positive. I am still nauseous sometimes waking in the night because of it and am waiting to see a specialist which could take many weeks in the UK. Any ideas as to what could be wrong with me would be greatly appreciated. I also suffer with bad burning mouth but no reflux. The BMS has been with me since I was diagnose hypo 4 years ago but has been a been better since the triple therapy.

Welcome to the gastroenterology community!  I would recommend waiting to get the stool test back which might show if something is wrong.
