Right index finger pain and sometimes numbness mostly at night when using mouse a lot and when i use it to type?

Nerve irritation: These symptom are simular to carpel tunnel but when they involve the index finer are more likely to be the radial or ulnar nerve and while you feel it in your finger the problem could actually be in your elbow. Try resting it for a few weeks if no relief you will likely need steroids, anti-inflamatory and physical therapy and if no improvement a nerve test called an "emg".
