¿What type of ailments can be treated with Yoga Therapy?

I genuinely enjoy being of service to others, it brings me
deep meaning and joy. Healing helped me step foot into the
person I really am, the joy of healing provided a shift, a new
way of seeing life. It is very gratifying to see a patient who
had to stand during 3 to 4 hours in front of a counter,
suffering from neck pain, after years of visiting doctors and
trying all sorts of therapies with no positive results, free of
pain after just six months of Yoga Therapy. Patients that
could barely move, unable to travel due to herniated discs,
become fully functional with no pain after a couple of
months, others with flat feet who couldn’t stand or walk for
long periods, victims of insomnia, asthma or other nervous
problems, living happy normal lives, free of inhalators,
sleeping and happily working.
