What can cause recurring facial droops that last 40 minutes to an hour and a half?

Hello. I had my 8th and 9th concussion back in September, a week apart. About a week later, I had a facial droop. It looked like I was having a stroke. I went to the ER and via CT it was determined that it wasn't a stroke nor was there a bleed. Since then I have had 10 more sporadic, recurrent, facial droops each lasting between 40 minutes to an hour and a half. Can anyone shed some light? Thanks!

Excerpt from Healthline - Facial Paralysis...

"Facial paralysis is a loss of facial movement due to nerve damage. Your facial muscles may appear to droop or become weak. It can happen on one or both sides of the face. Common causes of facial paralysis include:

infection or inflammation of the facial nerve
head trauma
head or neck tumor
stroke

Facial paralysis can come on suddenly (in the case of Bell’s palsy, for example) or happen gradually over a period of months (in the case of a head or neck tumor). Depending on the cause, the paralysis might last for a short or extended period of time."
