Havent read the full thread, am in the same boat, here is what I've been advised (no pins and needles though which is probably different):
Blood test - check b12, vitamin d, iron and thyroid etc
Take vitamin d, b12, iron, magnesium, co enzyme q10
Cut out caffeine, alcohol, stress as far as you can
Have you changed contraception recently
MRI scan and neurologist appointment
Stop painkillers for a bit - you can get headaches from over use
Get 8 hours sleep a night at regular times (dont lie in at weekends)
Drink 3 liters of water a day
Eat 3 regular meals no skipping meals
There are various medications you can take daily eg amitriptyline if all causes have been ruled out
Keep a headache diary, include scale of the pain, if you have taken painkillers and if you have your period
Keep a food diary to see if you have developed any allergies
