What do you do when you get sick at home? Wait it out, or if it isn’t a passing sickness, you go to a doctor. Same same here folks. I can’t even begin to tell you how many pharmacies there are dotted about all over the place. Not to mention that a lot of prescription drugs in the UK are sold over the counter here. Before I left I was desperately trying to get a backlog of my pill ‘Yasmin’. After numerous trips to the doctor, I eventually managed to get about 9 months’ worth. Only to arrive in Thailand and find it propped up on almost every pharmacy counter I visited. Big waste of time, big waste of energy worrying about it.
If you think you have a stomach bug my recommendation is to check into a nice hotel with an en-suite and wait it out in (relative) comfort. If you’re travelling solo, ask someone you’ve met or the hotel staff to check up on you once in a while. People are generally happy to oblige and will bring you water, Gatorade and meds if you require them. No one wants to see anyone suffer.
If you think it’s something more serious, you can get yourself to a doctor or hospital just like you would at home. A bit of research and you should be able to locate an English-speaking doctor in your area. You wouldn’t be the first traveller to fall seriously ill, and you wouldn’t be the last.
You should ensure that you have taken preventative measures to keep any serious illnesses at bay. Research online the required vaccinations for the countries you’re visiting and leave yourself plenty of time to finish the courses. Your government website or doctor can recommend these to you.
