Carpal Tunnel/Tendonitis

Hi! Here's my situations. I've had repetitive stress
injury for a few years and then I stopped typing and it
went away. Then I got diagnosed with tendonitis a couple
years back and had to wear the arm brace and stuff, do
physical therapy, etc.

So then I got diagnoses with carpal tunnel and tendonitis.
A few months later I went to another doctor, 2nd opinion,
and he said I had neither!! Apparently wearing the brace
had helped. I want to start weight training, and he
said I could, so I'm thinking great.

But, I still get sore from typing or lifting or
washing dishes. What do I have now?? Should I get
a 3rd opinion?

Thanks!
