In my opinion you should undergo a urine routine examination and fasting blood sugar test.
It is essential to rule out diabetes in your case.Pins and needles you describe can be a sign of neuropathy.
Vitamin B 12 levels should also be checked.
A X-Ray of Para -nasal sinuses should also be done.
As you describe large volume of urination it can be a sign of diabetes.
I hope this helps
