Tennis raquet?
I would go to a tennis shop that is part of a larger tennis facility. I would then have someone fit you for a racket, as far as grip size goes, and then see if someone will take a look at your swing. Your swing length and speed has a lot to do with what racket you should purchase. If you are using a racket that is strung poorly or is too heavy this could also account for your arm issues. I would spend the time and money to get the right fit on your racket since you are playing more than you use to. Then with experience you can make a different choice as you improve.
