The doctor will also probably write on it saying only physical examination done. Which I scanned and did some photoshopping as to avoid any unnecessary problems at the Thai airport ( in case they can’t read the English and what not )
I did it in a neighbourhood clinic and paid like $15 for it. just tell the doctor they only require physical examination. By the way the diseases stated has very obvious physical effects.
I also did check with the Thai embassy in Singapore in which they also said just need physical examination
