got woke up w/ intense pain, swelling, stiff knee, ect. I did not hurt it or have any history of injury? Its been 72 hrs and doesnt seem to get better. I iced it and taking pain reliever but doesnt seem to help the swelling or the pain? Will go to the doctor on Monday if it doesnt get better. I have been drinking alot of summer beer and coffee? Could the symptoms be from dehydration or could it be something else like gout, tendinitis or high cholesterol?
