Warhol was in so much pain that he spent the last two days of his visit to Milan in his hotel room at the Hotel Principe di Savoia.
After returning to the U.S., Warhol experienced the pain again on February 5th, at the Nippon, a Japanese restaurant located on New York's eastside (155 E. 52nd, New York, NY 10022; Telephone: (212) 688-5941). He was having dinner with John Rainhold and Sam Bolton.
He also appeared to be in great pain during his last public appearance at the Tunnel.
In the days to follow, Warhol went to see Linda Li of Li Chiropractic Healing Arts Clinic for a massage. According to Warhol, Li "mashed" his gall bladder during the massage.
Because of the severe pain he experienced following the massage, Warhol consulted with Dr. Linda Burke on Saturday, February 14, 1987. Dr. Burke suggested that he get a sonogram to examine the condition of his gall bladder. The first sonogram was conducted by Dr. Bjorn Thorbjarnavson, and the results indicated that the gall bladder was enlarged. On February 18th or 19th, Warhol went to see his physician, Dr. Denton S. Cox, to get a second sonogram which showed similar results. (Note: when the gall bladder was removed during surgery, it was found to be gangrenous.)
