Hi guys, seems like a great forum here. making my first post in here, just started wondering if i have symptoms of pd

my background: I know that I have bulging discs in my c5-t1, and my right side of my body arm, pec and leg have been weaker than my left for quite awhile now, since '08. I'm starting to feel slight weakness/numbness in my left arm a bit in the past year off and on.

concerning symptoms:

-i first started to take note when my right arm would tremble/shake when I yawn...and a bit embarrassed to say but also when I'd orgasm.

-when i walk at times, with well fitting shoes i'd stumble on flat ground due to one of my feet not being picked up enough. it doesn't happen enough where i have to think about it, but occassionially enough for me to notice.

-when i drink alcohol, i end up feeling very cold, even in mid 60's, 70's weather/temp...a lot of times unless it's hot i'll be shivering pretty bad, even if i'm in bed under covers. obviously even more so when colder out.

-im righthanded. yes my handwriting has deteriorated significantly over the years.

-not sure if i can hold my insomnia and sad moods to this, but its there. always tired throughout the day even though I have all the time in the world to sleep as much as anyone would want, but hardly can stay asleep for a couple hours at a time.

yes i know going to the dr is the best method, but im not sure if i can handle that right now. any initial insight would be helpful and appreciated.
