Always best to check for peripheral neuropathy - I experienced a slightly numb sensation just behind my nails, but much more damage to my feet. Vitamin B may help but always talk to your oncologist if you experience prickling or tingling sensations.

My fingernails had a very slight brownish tinge (not really noticeable). Best wishes.
