Suggest Treatment For Numbness And Tingling In My Finger

24hrs ago my index finger and thumb became numb and tingly, but not painful, only pressure type pain when the nail itself was pressed on, all day index fingernail deep magenta, very different color from other nails, with no capillary refill or blanching visible with any amount pressure- , but skin all around it is normal color, just stretched out & firm, now it seemed nail was lifting off its bed, I noticed tension on skin btwn nail bed and nail, so i popped it with sterile needle, huge amoount of clear fluid came out & pressure relieved- but no blood, and nail now fully white like the end where you cut it- what the heck?
