Just see your Doctor and obtain paid sick leave away from base in your home country.
Pilots in the Middle East need their full entitlement tor leave each year just like the managers... otherwise it is highly likely pilots will soon have a health event which if it does not kill you will probably loose you your license... and...your job.
Have a health event down route like a heart attack or a stroke and just like Gulf Air with 32year service Captain Rad Gammage... the Arab companies will most certainly abandon any expat. pilot down route to their fate... and if you do manage to survive...based on their past track record... they will under pressure reluctantly after 30 plus days waiting and hopping you will die...only then bring you home to base.
