numbnes & pain after wisdom tooth extraction

I know there are a lot of posts on this. I had my bottom wisdom teeth extracted 2.5 months ago. My inferior alveolar nerve was traumatized. I am seeing a deep muscle therapist and a TMJ pain specialist (I don't have TMJ but they are familiar with this issue). I am getting feeling back in my chin/lip, although it's hypersensitive. The discomfort is more in my eye tooth when I touch a certain area of my lip and my lip and the muscle in that area are still very tight and at times very painful. The TMJ specialist wants to put me on an anti-epileptic medication. I'm a bit resistant because there is substantial weight gain associated with these medications (which can be even more unhealthy than nerve damage). I have just had my 2nd steroid injection and although the tooth pain has subsided a bit, I am still having pain and the muscle is still very tight. Can I get any info on what treatment I should be pursuing aside from what I'm already doing? Can an acupuncturist help me? Has anyone tried the anti-epileptic meds and do they work? I pretty much understand what's happened with the nerve but can anyone explain what is happening with the muscle and does it need to be treated in a different way.
Thank you.
