gabriellesca, I would really encourage you to see a physical therapist at your earliest convenience. It's not going to get better on its own. Do you do alot of AutoCAD at work? That kind of precise mousing can really do damage.

My PT gave me exercises, a brace to wear when I type and sleep, and I had hot wax and massage treatments twice a week for a while. It's really important to nip it in the bud.

Your cycling habits do not sound good. Strengthen your core and relax you arms. And make sure that your bike fits you properly. Smile and breathe when you ride. And be aware of clenching your jaw. These are habits that will help you all around.

Best of luck to you.
