My sister in law wants to get straightened out, but she is apprehensive because she has post polio and pressure, exercising, and even walking too much makes her bones ache. She has numbness in the right cheek on her bottom and knows she doesn't want to take drugs or do surgery. She would like to try a chiro, but is worried she will ache for days. The only thing I though may be a little easier on her would be using an activator. Any suggestions?
