Residual Bell's Palsy
I have gone through your query and previous history.
As previous doctor mentioned, it is a case of Residual Bell's Palsy and it is not something else. People usually recover completely within 3 months of disease. The longer the recovery takes beyond the initial three months, the more severe the residual effects.
Residual effects can include eye problems (decreased lid closure / increased lid closure, dryness / excessive watering / watering during eating [crocodile tears]), nasal problems (running nose, dryness, collapsed nostril
), and others.
Treatment for residual effect can be effective at any time after it is noticed. There is no time limit. That is because the focus of the treatment is on re-coordinating rather than stimulating muscles.
But for excessive watering of eye, you need to consult an ophthalmologist.
Hope I have answered your query.
Wish you good health
