I recommend you see your surgeon to make sure you don't have an infection.
However, your symptoms are most likely related to nerve recovery following your operation. Many patients describe burning discomfort or shooting sensations.
You can reduce your discomfort by desensitizing the painful areas - try rubbing and squeezing these spots. Although unpleasant at first, these exercises will quickly become more comfortable and your symptoms will start to lessen.
