"i was given this shot in the e.r. for intense pain from a gallstone i had been dealing with and was scheduled to have removed. unfortunately, the gall bladder became infected. the shot did nothing, nor did a second dose. i had already been in pain and i rarely get relief if i wait until it gets that bad instead of taking medicines consistently to keep it under control. my boyfriend, on the other hand, had a bowel resection and was also in extreme pain despite having a morphine pump. he was switched to dilaudid and it relieved his pain immensely. as the reviews show, everyone is different. i don&#039;t know if i didn&#039;t get relief because it was too late for me so i rated it for that and for how well it worked for my friend."
