Reputable chiropractors do everything in their power to help their patients feel better as fast as possible with as few chiropractic treatments as necessary.
Depending on your specific back problem and symptoms, multiple visits to the chiropractor should start to bring you noticeable pain relief. Within one to four weeks of chiropractic treatment, you should feel significant relief and the frequency of visits should be re-evaluated.
Depending on the severity of your health issue, if you are presented with a recommendation for long-term treatment over a six month period, consider this a warning sign.
A crooked chiropractor may be more interested in your wallet, than treating your back pain! Talk with your Doctor and ask for a detailed explanation and set of realistic health milestones / expectations during the recommended period of treatment.
