Suggest Remedy For Blisters In The Corner Of Fingertips

hi i am 22 years old. approximately 2-3 weeks ago, my fingertips became very sensitive. shortly after, becoming numb. then today i noticed that i had small, non-fluid filled, blisters in the corners of my fingernails, towards the tip. after i washed my hands, the "blisters" began peeling off really thick chunks of skin, leaving the tips of my index and thumb raw and sore to touch. any suggestions would be appreciated. thanks.
