I hope that physicians refer people to physical therapy for their headaches. I read some of the posts and think that alot of people may be suffering from postural related problems that can cause headaches. I know from my mom that since her treatments she is more sedentary and her posture has been affected, now she has neck pain. As a physical therapist I try to have her advocate for herself to seek good physical therapy to address flexibility, strength and joint function. With all the other side effects of treatment, the last thing you need to deal with is headaches- that is probably easier to address than lack of saliva! So I hope this post may help people ask for physical therapy so that you can feel better and have less headaches!
