My dad was getting out of the shower today and suddenly got very dizzy and fell to the floor. He laid on the floor for a while till he could crawl to his bed. A few hours later he said he felt better and of course doesn't want to go to see a doctor. I found out today from my sister that yesterday mom handed dad a glass of water and his hand started shaking so bad he could hardly hold the glass. Are these connected? He is 82 years old. He is on the blood thinner medicine.
