Cause of pins and needles like itching? i dont have a rash, no allergies. i feel like my body is having anxiety, took allegra, (fexofenadine) not working.

#2 antihistamine: Are you taking any B vitamins that include niacin? Been out in the woods and touched nettles? If the itching is throughout the body might be a histamine reaction from foods or from skin dryness. Can also try 25-50 mg of Benadryl (diphenhydramine) which may make you sleepy. May also decrease the anxiety.

Pruritus : You should visit your primary care physician to get a comprehensive physical exam and blood work which would include your blood glucose to rule out Diabetes. If the initial work up is negative, it would be a good idea to visit a neurologist for a consultation. In addition, deficiencies or excesses of certain hormones, vitamins, minerals as well neurotransmitters may cause similar symptoms.
