I'm currently in Jomtien but return to Chiang Mai in a couple weeks. Hospital /medical doctor not needed (unless a prescription is needed), for the moment at least. A blood testing station and a pharmacy should be sufficient. Fascino might dispense without prescription, but I haven't physically gone to check yet.
Appreciate readers recommendations on Where for both a) and for b) in subject title,
in either Jomtien/Pattaya or in Chiang Mai. Thanks.
