Is throat/neck pain normal one year after tonsillectomy?

I'm 24 years old and I had a tonsillectomy last January (2010). The left side was a straight forward tonsillectomy. On the right side the tonsil had attached itself to the back of my tongue and surrounding areas in my throat. The right side required tying off of blood vessels and stitches. Needless to say recovery took a few weeks and was pretty painful. Everything was better for a couple of months following this, apart from my jaw occasionally locked causing a painful click in the joint when trying to open my mouth. The lock jaw has become increasingly worse over recent months and I have developed a persistent pain in the right side of my throat and neck. The pain comes and goes, but is sometimes so severe that I am unable to swallow or eat. When really bad the pain radiates into my neck and ear. When drinking fluid I get a sharp stabbing pain in my throat which feels as if it is at the base of my tongue on the right side at the back of my throat. The pain is severe, as if there is raw skin exposed in my throat, but there is nothing to see in the areas of my throat that I can view with a mirror. Has anyone else had these problems with either pain or lock jaw after tonsillectomy, bearing in mind it is now thirteen months since my procedure?
