PICK A DIFFERENT CLINIC IF YOU WANT TO GET YOUR PAIN TO A COMFORTABLE LEVEL ... please read on. Horrible experience with this man from the beginning (Chen Zongfu). I was at this pain clinic for about 6 months and left to find a new one because of how all around horrible it was. Could never understand him at all and never actually had my pain at a comfortable level, didn't seem like he knew what he was doing at all.Terrible diagnosing & mind set before he even sees you.Impossible to understand, he sounds literally as if he had just read the book "English for Dummies".Doesn't listen to patient or work with patient at all.Tells you "Okay, yes. Okay, yes. That is what will do!" and does the complete opposite ... don't waste you're time going here, pick a different clinic. Even the nurses/secretaries are rude and careless with calls, appointments, general attitude and everything.
