Hello and welcome to HCM,
Trauma to the thumb has caused the blood to accumulate under the nail.
Your primary health provider has drained the blood under the nail by removing the nail.
Now you have mentioned that you are feeling numbness over the tip of thumb.
This numbness can be due to trauma to the nerve supplying the tip of thumb.
In some instances the injury to the nerve is reversible and it heals spontaneously after couple of days.
So wait for couple of days and observe if the numbness still persists.
If it disappears it is fine.
But if it does not, I suggest you to consult an orthopedician to assess the nerve function.
In the mean while get sterile dressings on the wound on the thumb.

Thanks and take care
Dr Shailja P Wahal
