In spite of staying fit, using lifts and equipment to take the load off myself, and also watching my body mechanics, I still end up with shoulder tension which result in headaches. I always have.
I have tried MDs, massage, stretching, narcotics, NSAIDs, analgesic rubs, hot/cold packs, showers, baths, yoga and plain waiting it out. One trip to the chiropractor and it's like magic. I go about once a month.
As for the baby, I wouldn't do chiropractic unless she was symptomatic and we had explored all other possibilities. Maybe not even then. The swollen legs would get a trip to an MD as well.
Chiropractic is a complimentary medicine, it isn't a cure all. But it sure has given me a better quality of life
