Is it normal that my hands shake a little after i workout?

I am 5'11'' , 152 lbs, 19 yrs old .. I am going to gym for two weeks now.. I started by lifting the lightest weights but I have improved in these two weeks.. Sometimes I feel an unusual but bearable pain in my left shoulder, sometimes in my right too but mostly in the left shoulder while working out.. Then when I come back home from gym after about an hour of working out, my hands shake a lil bit.. Not so much that I cant lift a glass of water without dropping but like I hold my cell phone in hand and I clearly see my hands shaking .. Is it normal?
