When to my family dr and he said same thing,neurological and will go ,but when ,my hurts and looks like blisters or bad acne and are trigger by sweat and stress.
Gabapentin helps,but i still have then every month and really painful ,and all the areas around hurts as result ,so I'm still with the puzzle as you are,with Benadryl cream,tablets,goldbond spray to cold down my sweaty areas and other than that ,nothing else is working ,
Hope someone finally get a logic answer beside the one Russell mentioned.
