Hi,

 

I am 34 year old male from India,Mumbai. I have been experiencing an acute problem since last 6-7 years , whenever winter sets in (around Nov) in this part of world .. my head starts getting heavier / numb during early  mornings and it last for almost 60 - 90 minutes and after that everything is normal. But some day this effect might last for 5-6 hours also.. very rarely. This problem ideally continues till January end every year.

Not able to figure out what is the reason for this kind of problem and is there any solution to it.
