3rd Nerve Palsy

Definition
Third nerve palsy describes a condition involving the third cranial nerve (also called the oculomotor nerve), which is responsible for innervating some of the muscles responsible for eye movement.
Description
Third nerve palsy results in an inability to move the eye normally in all directions. Injury to the third nerve can occur anywhere along its path, from where it originates within the brain to where it innervates the muscles that move the eyeball. Third nerve palsy prevents the proper functioning of the medial, superior, and inferior recti, and inferior oblique muscles. As a result, the eye cannot move up, down, or in. When at rest, the eye tends to look down and to the side, due to an inequality of muscle functioning. The muscle responsible for keeping the upper eyelid open (levator palpebrae superioris) is also affected, resulting in a drooping upper eyelid (ptosis).
Causes
A wide variety of conditions can result in third nerve palsy, including pressure and damage from tumors; blocked arteries or aneurysms leading to oxygen deprivation of nerves; meningitis; vascular complications of diabetes or high blood pressure; complications of migraine headaches; traumatic injury; birth injury; congenital defects; and conditions that strip nerve fibers of their myelin coating, resulting in slowed nervous transmission.


That's just a little on 3rd Nerve Palsy... here's an update on me now!

Anyway I went to another doctor today and he said that the 3rd nerve is not damaged, which controls the eyelid and eye, however it is weakened. I was told to put cold compacts on it along with taking ibuprofen. If things don't get better within a week he said to go back and that he would do an MRI. He also said if things get worse or if I start feeling a tingling sensation also to return because it could be 3rd nerve palsy!

I'm hoping things get better :D
