Your wrist problem is likely to be due to de Quervain
tenosynovitis- affecting two of the tendons in the wrist.Other problems like a Carpal Tunnel Syndrome
also needs exclusion.Your doctor will be able to guide you about treatment after making a specific diagnosis.
The pain you mention outside the shoulder blades are likely to be unrelated to your wrist pain
and is likely to be due to myofascitis.The dizziness
you complain about needs more detail before it can be commented about.
It might be ok to wait to see your doctor as your problems do not seem to be of an urgent nature.
Hope this helps!
