Janus, very sorry to hear about your accident, but good that you are on the road to recovery! Thanks for sharing, and it is something that we should take into consideration always be alert! I am assuming you have medical insurance coverage for your holiday?
For those wondering - if the medical staff have western accreditation/qualifications you will probably have care equal to or better than hospitals in your home country. However, there are not many hospitals like that. Bumrungrad Hospital in Bangkok probably has the greatest numbers of western accredited doctors - but it also one of the most expensive.
Self diagnosing is tempting - but not always accurate and if you can find a good, reliable doctor I would recommend that. While the age of the internet is amazing, it doesn't match at least 12 years of training plus multiple years of experience for a good doctor to figure out what is wrong.
