I was a pre-med major and tried getting into med school for four years while working in research. Not a doc but I have some background in this area of study.
Chiropractors are good in their niche. Their niche is the spine and its allignment. They relieve muscle pain associated with a misaligned neck and/or back. There are two different philosophies with Chiropractors. Some believe what I stated above and limit themselves to healing what they can heal. Others believe that they can heal all sorts of maladies from high blood pressure to kidney infections to carpel tunnel. They base this on the idea that the nervous system is the core and if it is unhealthy, it creates other illnesses.
The first idea is great. Chiropractors are great at treating the spine. What others believe is a crock and is why many chiropractors are seen as quacks. A chiropractor has no better ability to heal your wrist than you have of healing a sick puppy without help from a vet.
Go to a chiropractor first for lower back pain, neck pain, whiplash and scholiosis, but go to an MD for anything else. The best route for wrist trouble is to go to a General Practitioner and then be referred to a orthopedic doc.
Just a side note, it takes a high GPA (3.5 or higher) and a high MCAT score to get into med school. It takes a 2.5 to 2.7 to get into most chiropractic schools without a problem.
Personal experience:
I have been a patient under 3 different chiropractors. 2 were really good and helped my back pain, one was a quack and I only visited him twice. I injured my neck when I was a wrestler in high school. I had a reverse 13 degree curvature in the cervical vertebrae. I have also had problems with my mid-back from being a waiter in college (carrying lots of heavy trays only on my left side). They have stopped allt he pain I had and have done great things, in regards to my spine.
Sounds like you may have a full-fledged quack on your hands. I'd say
RUN!
Good luck with your wrist. Remember...GP then orthopedic specialist for this problem...
