I felt in worse pain than before. Specifically, I told them of my past neck injury. They reassured me their therapists could handle it. At the end of the session my left side spasmed. I explained that this has never happened and the woman told me not to sit in front of air conditioning for the next few hours. If they had been professional, they would have reworked my back. Instead I was given a cup of water and sent of my merry way. What a dump!
