Tremors stopping?

My dad (86 Years old) was diagnosed with Parkinson's a number of years ago, and is in the later stages.  He has numerous other health issues - High BP, Orthostatic BP, spinal stenosis, diverticulosis, congestive heart failure, has had by-pass surgery, recently had a mild heart attack at which time numerous blockages were found - but a stent was not possible.

He has been in (out, and back in) the hospital for two weeks due to diviticular bleeding.  when he was admitted he was having his tremors as usual (both arms, sometimes both legs, and somtimes his chin).  During his stay he received 11 units of blood.  Now, he barely has tremors - ANYWHERE!  None of the doctors or nurses can explain this to us.  

Any one else experience this?

I have PD and when I am ill my tremors are awful. I have had a sinus infection and I was reduced to a wheel chair and my family feared to leave me alone. Once the antibiotic worked I was on my feet walking a mile or 2 a day again. Everything effects a person with PD an argument can turn me into a shaking figurine stuck in a door way.
I hope your Dad does well and has no more complications.
