DC Young Fly's partner Jacky Oh!'s died as a result of complications from cosmetic surgery, complaining her head was "burning" just hours before her death, TMZ has learned.
According to the autopsy report, obtained by TMZ, Jacky flew to Miami in May to undergo a procedure where she had liposuction and fat transferred to her butt ... aka a BBL.
The surgery was completed May 30, and Jacky was prescribed Ciprofloxacin (an antibiotic), Oxycodone (a painkiller), and Ondansetron (anti-nausea).
Shortly thereafter, the 32-year-old began to get a headache, returning to the surgeon for a post-operative appointment ... she then decided to get a massage to help alleviate her pain, and was advised to take ibuprofen and to stop taking the Ondansetron.
On the night of May 31, Jacky began to feel her head was "burning" and began to have difficulty speaking, Jacky was with her aunt, who called 911 -- but Jacky went unresponsive before they arrived ... and was pronounced dead at the hospital at 11 PM.
The autopsy report states Jacky had swelling in her brain and extensive bleeding of the skin around her torso.
A since-deleted social media post before Jacky's death claimed she was in the city to go through a "mommy makeover" with Dr. Zachary Okhah.
Dr. Okhah spoke out shortly after her death, but didn't address the situation directly -- instead stating his office "remains devoted to the highest quality medical care." He added, "All aesthetic procedures are performed in a hygienically safe environment to universally recognized medical standards."
