I had some partial facial paralysis too a couple years ago when I had Lyme Disease. There was a point where we both went to Harvard Square and sat by a flower shop and I was self-conscious about smiling weird. They gave me some Ibuprofin for the inflamed facial nerve and some eye drops and Lyme Disease meds and it went away after a couple weeks. It made me think of that when you mentioned Melo's malady.
