You have what is called aberrant regeneration of the facial nerve. The facial nerve is the one that is affected in Bells Palsy. This occurs when the nerve is injured. As it recovers, abnormal connections are made. This is why you tear when you chew, etc. There has been some success with Botox treatment to minimize the effects from the aberrant stimulation (tearing), but this is temporary. The drooping lid can be lifted up with surgery.
Hope this helps and thank you.
