It sounds that you have tried a number of regimes, with ongoing and unresolved symptoms.
I would suggest you alter your training regime but decreasing to a bear minimum. Given the chronicity of symptoms, try ceasation for 4 weeks. I appreciate your Thailand experience and time constraints, but the longer you look for quick fix answers the longer and more chronic it will become.
You mentioned you attended a Podiatrist and "bought" custom insoles. Were these taken form a corrected cast? Was a full biomechanical performed? As advise given muscle group strength assessments are required to exclude imbalances, as is a functional limb length measurement.
Normally for this case I would expect an everted or valgus rearfoot. With nearly all pronatory complaints such as yours, I would see a Gastroc/Soleal Equinus. So, srtretching the calf mucles individually is paramount. If their is a functional difference greater than 0.5 cm, then a 0.5 cm heel raise should be added to the shorter side. Deep tissue massage is uncomfortable, but your physio and his/her fingers deeply working the Pre Tibial would also benefit.
If the Insoles are NOT Orthotics, then have them reviewed. Again I am not an advocate of Rigid orthotics, but an average male approx 80-85kgs would benefit from a semi flexible 4mm polypropylene orthotic witha soft tissue supplument.
Food for thought..interested were you go from here. But do dramatically knock off the training until or allowing for healing.
