May 15, 2012 -- A medical report compiled by the family physician of Trayvon Martin shooter George Zimmerman and obtained exclusively by ABC News found that Zimmerman was diagnosed with a "closed fracture" of his nose, a pair of black eyes, two lacerations to the back of his head and a minor back injury the day after he fatally shot Martin during an alleged altercation.

Zimmerman faces a second degree murder charge for the Feb. 26 shooting that left the unarmed 17-year-old high school junior dead. Zimmerman has claimed self defense in what he described as a life and death struggle that Martin initiated by accosting him, punching him in the face, then repeatedly bashing his head into the pavement.

Also today, a trove of documents are being examined by lawyers for both the defense and prosecution as part of discovery in Zimmerman's trial -- including 67 CDs worth of documents, video of Martin on the night of the shooting, his autopsy report and videos of Zimmerman's questioning by police.

Zimmerman's three-page medical report is included in those documents that the defense could use as evidence.

The morning after the shooting, on Feb. 27, Zimmerman sought treatment at the offices of a general physician at a family practice near Sanford, Fla. The doctor notes Zimmerman sought an appointment to get legal clearance to return to work.

The record shows that Zimmerman also suffered bruising in the upper lip and cheek and lower back pain. The two lacerations on the back of his head, one of them nearly an inch long, the other about a quarter-inch long, were first revealed in photos obtained exclusively by ABC News last month.

But the report also shows Zimmerman declined hospitalization the night of the shooting, and then declined the advice of his doctor to make a follow-up appointment with an ear nose and throat doctor.

In addition to his physical injuries, Zimmerman complained of stress and "occasional nausea when thinking about the violence." But he was not diagnosed with a concussion. The doctor noted that it was "imperative" that Zimmerman "be seen with [sic] his psychologist for evaluation."

According to the report, prior to the shooting Zimmerman had been prescribed Adderall and Temazepam, medications that can cause side effects such as agitation and mood swings, but in fewer than 10 percent of patients.

A neighbor told ABC News that the day after the shooting he saw Zimmerman as he spoke to officers outside his home. He too recalled seeing black eyes and significant swelling -- as well as a bandage over his nose.

Moments after the shooting Zimmerman told eyewitnesses he shot Martin in self defense. He later told officers his head was being pounded into the pavement and that he feared for his life, but that it was only when Martin seemed to reach for the gun wedges in his waistband that Zimmerman drew his weapon and fired directly into Martin's chest -- killing him.

The medical notes may bolster Zimmerman's claim that he acted in self-defense because he was being attacked. However, the prosecution contends that Zimmerman instigated the confrontation after profiling the teen, who was walking home after buying skittles and ice tea. They prosecution says Martin was breaking no laws and was not disturbing anyone as he walked back to his father's girlfriend's home.

Zimmerman was granted a $150,000 bail and has since been in deep hiding since his April 20 bail hearing.
