Hi there i am a 24 year old male who

Patient: Hi there i am a 24 year old male who has drank fizzy drinks milkshakes or anything of that kind literally all my life, apart from in the past 2 years whenever i drink fizzy pop still/fizzy flavoured water milkshakes or anything of this kind i feel very sick i also get a pain behind my eyes. I have been tested for diabetes several times and it comes back normal i also suffer from alot of water infections. I have seen people say it could be a caffiene allergy but i can drink tea and im fine. I do not get pain in my stomach but i do get a pain just under my rib cage on the left hand side of my body. ThanksMarcus
