Persistent thumb numbness after hook grip — should I be concerned?

I've been practicing hook grip for a few weeks. Yesterday, I did SLDLs with 90 kg for 4 sets of 8. It wasn't very heavy for me, but it was putting a lot of pressure on my thumbnails.

I previously slightly tore the nail/skin around my right thumbnail because I don't notice minor cuts while lifting.

Yesterday, after my SLDL session, my left thumb felt a lot of pressure, and the upper part of my thumb became numb. I don't know whether it happened during set 1 or set 4. After that, I did some light ab work and left the gym.

The numbness didn't improve. I slept, and it's now been about 12 hours, but the numbness is still there. It may have improved slightly, but I'm not sure.

I can move the thumb perfectly fine, and everything else feels normal. The numbness is only in the distal phalanx area, around the nail.

Has anyone experienced this from hook grip? Should I be concerned or just give it some time?

I have been training and eating seriously for 1 year and ate in deficit to go from 75kg to 63kg bodyweight I thought I would get to 15% bodyfat atleast but I still look over 25%

Currently I am 18, 5'7", 63.60kg and maybe 25% bodyfat I can Smith squat 100kg for reps Smith machine bench press 65kg for reps RDL 130kg for reps Barbell curl 35kg for reps

But I am still so small, my arms are 13.5 inch, only gotten leaner with same size as my 75kg physique My legs are 22 inch

I did gain some muscle though, I think I would get to 15% bodyfat at 57kg, but what if I don't have enough muscle to look good?

what should I do from this point?
