The differential can be several things. Where was the numbness exactly? A cause of numbness of the index finger and middle finger is carpal tunnel syndrome. It usually also has sensory changes of the palm at the thumb, index and middle fingers, and the ring finger on the side near the middle finger. I am not sure if you have these other features or not, but I will elaborate on carpal tunnel syndrome.
Carpal tunnel syndrome is a compression/entrapment syndrome of the median nerve at the wrist. It usually results from excessive use of hands and occupational “microtrauma”. Other causes include hypothyroidism, amylodosis, and arthritis to name a few. It may also arise during pregnancy and resolve after delivery of the child. The sensory changes usually are worse at night. Patients may complain of having to shake their hand to wake it up. If it is a recurrent problem (day and night for years), you may develop atrophy of muscles of the thumb supplied by the median nerve.
For now, if this was an isolated event, you may wish to monitor. If it is a recurrent event, you should have your primary physician evaluate you. You may wish to purchase a wrist brace at your local pharmacy. If the problem becomes disabling, surgery is an option.
Thank you for using the forum, I hope you find this information useful, good luck.
