Why did I feel so much pain during laser lipo & cellulaze treatment?

I just had laser lipo and cellulaze of my inner/outer thighs and above my knees. I was given lidocaine injections at the start of the procedure but continued to feel pain. The doctor kept giving me more lidocaine but it wasn't taking the pain away. I could even feel the needle when he was stitching me up. The pain was so bad he had to stop the procedure. At the end, he couldn't even wipe my leg with the towel without me crying. Why did I feel so much pain despite getting so much lidocaine?
