Should i be nervous going to a chiropractor? i have horrible misalignment issues and tight/stiff body but i am skeptical of someone cracking it. pt hasnt worked and im miserable with pain and headaches?

Unfortunately, chiropractors vary with training and skill. Some are very careful and conscientious, but others are dangerous. Contact the local Board of Chiropractic Examiners and check disciplinary records. Also talk to orthopedic surgeons as to their favorites. Alternatively, you could find an Osteopath, as these are certified physicians who have been trained in manipulative approaches.
