Worsening Balance

My husband had an episode that he was taken by ambulance on May 4, 2019 that was misdiagnosed as vertigo and inner ear trouble.  We were told to expect this vomiting, loss of balance, etc to happen again….typical Wallenberg symptoms we now realize.  His balance was terrible for several weeks, but was able to walk without aid after some time. Fast forward to July 19^th 2019.  He rolled over to put the phone on the bedside table and instantly began to vomit and had no balance.  By noon the next day, the vomiting stopped, but he had absolutely no balance at all and could not walk.  By Sunday, the 21^st, his lips began to tingle, he lost feeling in half of his face and had a hard time controlling his arm movements. Within 15 more minutes he lost his ability to swallow.

Immediately went to ER where, after a CAT scan, we were told he had had a stroke within a few months (May 4^th episode we are sure) and they would do an MRI the next morning.  Long story short, he was finally diagnosed with Wallenberg Syndrome and had a brain stem stroke,and had a feeding tube inserted.  Thankfully, he had a spontaneous recovery for swallowing within a month, although he was very limited in what he could eat.  He spent 3 weeks in intense rehab and came home with a wheelchair and a walker. 

He was released from physical therapy walking pretty well on his own in late October.  My question is this….for the past month his balance is worsening.  For the past few days he has said that the “tilting” feeling has returned and that he is having trouble with feeling his right leg on floor.  The droop in his eyelid is a little more pronounced that what it was. We were just wondering what others have experienced in their recovery.

Thank you very much
