I Had Tennis Elbow Surgery A Little Over 3 Months

I had tennis elbow surgery a little over 3 months ago. In the past couple of weeks I have been having soreness, some burning sensations (similar to what I had prior to the surgery), and some occasional pain around the area where my surgery was performed. My shoulder is also a little sore as well. Is this normal and is it possible this will get better and go away, or should I notify my surgeon of what is happening?
