Just make sure you have a good treatment goal...there is no need for lifetime treatment.
It seems the Chiro I go to regularly right now, makes sense he has me doing excersise at home, Cerv traction, head weights, forming thingys you lay on, wooble chair. My xrays showed not much curve in neck, thoratic cob (bend in spine). So I have been being adjusted 3 times a week for the first 3 months then on to maintenece. The neck adjustments took some getting used to thats for sure.
I was always sceptical of chiros but now think they have lots to offer, they teach the whole lifestyle approach which makes sense also. This helped convince me they can help, when i did the wobble chair thing I noticed it would cause a pain in my left testicle when I moved to one side. After a while thinking not much of it told the DC and he said thats a pinched nerve. He adjusteted me on my side where they push bent legs down and after that the pain in the nuts was gone. It has come back a bit to a lesser degree now and then but much less than before and very infrequently now, it suprised me how well it worked.
Anyhow It seems they push that being adjusted is a lifelong thing, yeah it keeps the money coming in for them. But it makes sense to me especially if training heavy and stressing my spine pretty hard. Does 2 times a month sound about right for maintence? Im sure it varys with the individual. My insurance covers 40 visits a year so that should have me covered.
