I have pain in the right index finger, sometimes also experienced numbness, especially when I use a lot the computer mouse or if I type a lot.

These symptoms are very similar to carpal tunnel syndrome, but when it also involves the index finger, it is likely to be due to a problem with the radial nerve or ulnar, and even though it sits on your finger, the problem really could found in the elbow. Try to rest for a few weeks and if not relieved, it may require taking steroids, anti-inflammatories or perform physiotherapy. In case this is not better at all, it may require an analysis made ​​of the nerves called "electromyography.
