Oh dear! That sounds real bad, and no one can identify what the issue is? I know it sounds stupid, but does keeping your head warm help? Like drinking lots of warm water, it's an Asian thing, keeping your body warm keeps it healthier. And another thing, you know when people hurt their wrist or ankle, they may wear a support or brace. Not sure if wearing a tight fitting cap might help sometimes.
And I'm serious, not joking here!!!
