Didn't know that

I started keeping a journal on Greg's PD, at our last visit to the Doctor I realized that I had to be more in touch with what he doesn't always tell me, so I make it a point to ask Greg how he is feeling more often that I was.  Today he told me that sometimes he has trouble raising his arms to shower or get dressed.  This is the first I have heard of this. I am not alarmed by it but am curious as to why this is happening, I am hoping it isn't the start of a permanent trait.  I will be curious to hear our Dr.'s response.  It isn't all of the time, it seems to be after he has taken his first dosage of meds.  I know I am not alone, in my times of worry, fear and questioning, "what next" seems to be the word of the day.  But here is where the WALK comes in to play, I will walk with my head held high and will get through as I always do.
Keeping the faith.
