I always experience numbness in my fingers on my right hand. what could be wrong? thank you.

Carpal tunnel: If the numbness is more of the palmar side of the hand and spares the 5th finger, it is likely to be carpal tunnel syndrome.

Several things: If you only have numbness in the finger on one hand it suggest that this is likely related to some degree of anatomic nerve compression rather than a concerning toxic-metabolic nerve problem(like in diabetes). It could be related to compression of one of the nerves at the level of the wrist, elbow or even from the neck. You'd be wise to see your doctor for an inperson evaluation.

Neuropathy: This sounds like neuropathy. This could be caused by multiple things such as medicaitons, metabolic disorders, blood disorders, impingment syndromes. The best thing to do woul dbe to see your doctor so appropriate testing could be performed.

Numbness in hand: may reflect an irritation along specific nerves that are responsible for sensory in those areas. Only a detailed physical examination and /or lab tests, studies can diagnose your particular case. The nerve may be irritated in your wrist as in carpal tunnel, or in your elbow or near your neck as in cervical disc pathologies. Central causes do exist as well as in MS. See your Doctor for guidance.
