Your husband has generalised pruritus
with pricking sensations.
He is having habit of alcohol also.
There are many causes of generalised pruritus.
He should be investigated to find out the internal cause.
,liver diseases,renal diseases,blood disorders,malignancies, endocrinal disorders..etc should be ruled out.
If everything is normal, the cause may be alcholism.
He should stop to take alcohol.
Please consult dermatologist
for perfect diagnosis.
Oral antihistaminics and steroids
in tappering dose would be helpful to alleviate the symptoms.
I hope you got my answer.
