Constant headache throughout. Here.

I have been experiencing constant headache throughout the day for the past couple of years. I sometimes feel nauseautic and have slight memory issues. I was prescribed Nexito Forte 10mg during 2015 which i stopped myself without consulting the doctor as soon as my pregnancy was confirmed. Recently my neurologist had suggested I get MRI done for my brain as I had been facing numbness in some parts of my body. The report had the below impression: 1. Left anterior temporal fossa arachnoid cyst 2. Multiple hyperintense foci in both upper centrum semiovale are to represent microvascular disease changes of the white matter or demyelinating disease 3. Minor chronic pansinusitis I was prescribed some pain relievers however of no much benefit. I am currently staying in Malaysia and fellow Indians say that the medical thing in India is much more advanced than here. Please suggest what do i do as have stopped visiting the neuro here.
