Compression of the median nerve causes tingling and numbness in the thumb, forefinger, middle finger and on the thumb-side of the fourth finger. It may also cause pain in the forearm and occasionally into the shoulder.
I'm not sure if you are saying that there is NEW thumb numbness or if you are saying that the thumb numbness you had from your carpal tunnel syndrome condition is still there? If the latter yes it can be normal and it may take several weeks to months but it should gradually improve once that compression on the median nerve has been released. If it's new, then possibly the median nerve still has some swelling and inflammation about the nerve from the surgery itself, and it should improve as your condition improves. The other possibility is that the median nerve was knicked, which is a risk factor for carpal tunnel surgery
Go to nearest emergency room for cardiac evaluation immediately....
The median nerve is also called the musician's nerve. Either can become compressed because of the repetition while playing.The ulnar nerve compression (aka cubital nerve compression) affects the pinky and part of the fourth finger. Those who play a lot of guitar can have this problem.The median nerve compression is also called carpal tunnel syndrome. The median nerve affects the thumb, the second and part of the forth. Damage prevents a person from grasping with the thumb. This is called: "the Ape Hand" as apes can not oppose their thumbs. The musician will not be able grasp their instruments.

Generally finger numbness is a result of conditions that affect nerves and/or blood vessels that supply the fingers. It is also associated with tingling. It need to be sorted out if the problem associated with only left thumb. Frequent symptoms are referred as finger paresthesia.
Probably some swelling or inflammation putting pressure on a nerve.

Pinched nerve in shoulder or c-spine
Tingling and numbness on left hand thumb and index finger may be caused by nerve damage or carpal tunnel. If any injury has happened to that hand, there may also be a bone fracture causing those symptoms. Another likely possibility is onset of diabetes.
Numbness in hands could be caused by carpal tunnel syndrome or excessive use of alcohol. Other reasons include a vitamin deficiency and a range of major diseases, such as syphilis or diabetes.
The median nerve, this nerve supplies feeling and movement to the thumb and "thumb-side" of the hand.
