The trouble is, most of the symptoms you mention can have a number of different causes - and they are not all to do with D.
So, in a general way, if you are getting weird symptoms when your bg is within the 'normal' range, then sure, check it out with the doc.
But you may also be interested in these bits of info:
Peeing a lot - yup, often caused by high bg. usually the bg has to be over about 10mmol/l in order to trigger the kidneys to work at pulling the sugar out of the blood carrying that extra water too. If bg is below 10, then it is likely another reason. Drinking more in hot weather? Upping water intake when switching to Low Carb? Shedding water retention when cutting down on carbs. Some sweating patterns are linked to neuropathy, but I don't know the details. Could be lots of things...
Ditto for being thirsty.
Night sweats: well, this is a can of worms! peri-menopause, menopause, forgetting to turn off the central heating, the cat using you for a pillow, cheese, dreams, food intolerances, big meal the night before, alcohol, hypers, hypos... the list is endless. Best to check your bg when you wake up sweating, otherwise lots of other things to investigate...
Blurred vision - blood glucose levels can affect the liquid in the eyeball, affecting its refractive length. When the bg levels are stable, the muscles around the eyeball learn to adjust (automatically) and we see clearly. When bg fluctuates, it takes a while for the muscles to adapt - and things seem blurry. But of course, blurred vision can be caused by many other things, including creams, tiredness, muscle weakness... again, the optician is your friend! just don't go spending a fortune on glasses until your bg has steadied down, in case your prescription changes again.
This probably didn't help you at all, but hopefully it suggested that if the problem continues, get it checked out by doc.
