I got trigger finger surgery in Jan 2012,had to have the surgery again in the same place after having more severe pain after first surgery.

In Jan 2012 I had my first surgery for the trigger finger pain,I followed up with my dr and complained of severe pain during my follow up,I was told to do exercises to my fingers to relieve pain. Months after my surgery and still no relief I sought out a second opinion.The doctor assured me that the trigger finger was still there in the same finger I had the previous surgery on. I don't know if this is common the first doctor who did my first surgery did tell me that the surgery is successful. I have now had my second surgery this year for the same problem. I just want to know if this is common or was something not done correctly during my first surgery.
