@amytro, I found an excerpt from Mayo Clinic regarding pain medications that may be applicable to what your surgeon has said about your upcoming second surgery and pain control (https://www.mayoclinic.org/chronic-pain-medication-decisions/art-20360371),

"Benefits and risks. Research shows that over time, your body adapts to these medications, and they bring less and less pain relief. This phenomenon, known as tolerance, means you need more of the same medication to achieve the same degree of pain relief. Long-term use of opioids may lead to dependence on these medications and, eventually, addiction.

The longer you use opioids, the greater your risk of becoming addicted. However, even using opioids to manage pain for more than a few days increases your risk. Researchers at Mayo Clinic have found that the odds you'll still be on opioids a year after starting a short course increase after only five days on opioids."

@amytro, have you discussed this concern with your surgeon or medical provider? Have they discussed an alternative or complimentary management plan with you?
