MS with Bradykinesia ?

Hi everyone , not new to the forum but a change of name.
I’ve been living with MS for most of of my adult life and the progression has been thankfully slow. During the last year though I’ve developed something called Bradykinesia - this means that I shuffle when I walk ( with a rollator ) but then my legs will freeze. It got so bad since January that I can stand Ok but cannot turn. I saw my Neurologist last week and I was told that whilst it’s definitely not Parkinson’s but a Parkinsonism Symptom and was put on a drug called Levodopa. Just wondering if anyone else has heard of or has this?
