Many times when I play the bass guitar, I find out that my fingers become swollen like as if i placed them on a hot surface. How can I avoid these types of injuries.

However, there are correct ways to handle your musical instrument without having to cause injury to your body; so you should learn about how to place your fingers on the strings and fret board properly.
If you are having allergic reactions to strings or friction, then you can make use of vinyl or latex gloves to avoid direct contact of the strings with your fingers.
