Lana,

My friend's sufferings are not due to weather. Its because of excessive strain applied to fingers by using Laptop/Computer for very long hours.

When he initially felt the pain, he didn't care much and hence this intensified pain.

He needs two things.
1. Rest.
2. Natural treatment.

Regards,

I agree. I am in the computer field but cannot say it was due to data-entry as it was left arm.

All I am saying is make sure that your friend has tendonitis and not something else. Take a second opinion before you spend huge amounts of money on physio-therapy.
