Body is messed up really tight and one shoulder is higher than the other. i think its the cause of my chronic headaches but im afraid to go to a chiropractor. is there anything else i can do to get this fixed? thank you?

Many options: There are many superb chiropractors who may really help but some are less trustworthy; I prefer chiropractors who use gentle techniques like Direct Non-Force and Network. Your Dr. or friends may be able to recommend one. But Osteopaths who do manipulation are all trustworthy- see https://tinyurl.com/yxgutjgb A good physical therapist or massage therapist may also help; research to find the best.
