I am 62 years old. Weight 70 kgs now after maintaining 68 kgs in the previous 2 years. My lipid profile is controlled by taking 1 stanlip 145 mg at night only for last 7 years. For a very marginal sugar level of 130 (fasting) &150 (postprandial), I take Glyciphage SR500 1 after lunch (2 PM) and 1 after dinner (9 PM). But for the above I am normal. I normally do some deskwork watching TV or listening to music and go to sleep after midnight. forte last 9 months or so, at about 3 am, about 2-3 hours after starting my sleep, I wake up for urination and I experience severe itching on the OUTER SURFACE ON THE TOP OF MY HEAD. Except for hair on the sides and back of my head, other middle and top portions are bald. Mainly the itching occurs on bald portions especially not on the outer surface, but quarter/half cm beneath. Itching occurs at different points or patches on the bald surface. If I scratch one itching patch/point, itching appears to vanish, but itching starts at another point/patch on the bald portion. It continues for about 30 mts to 1 hour and I go to sleep involuntarily. Itching also happens at the tip of my penis and the inner side the outer skin near the tip. After scratching intensely to the extent of getting pain and washing off, I go back to sleep and it is ok after that. This is happening in20 out of 30 days in a month. In fact the itching wakes meup and after urination it takes 30 mts to 60 mts to start sleeping again. I am in the bed from 1 to 7 am and out of this I lose 1 to 1 1.5 hrs sleep. Why is this itching happening? Pls suggest simple remedy without starting dosages of medicines.
