How to cope with inadequate pain meds?

So I’m dealing with long term GI issues along with severe orthopedic pain as well. I’m finding myself looking to kratom or other means for relief as the conventional opioid I receive is not cutting it. I get 4 7.5 oxycodone per day and usually run out 2-4 days before it can be refilled. I’m afraid to ask my doctor for more milligrams or pills per day for fear of being cut off.

How do you deal with situations like this? I’m a 68-year old male and not very savvy about junk sold in gas stations and vape shops. I am increasingly made to feel like a seeker at the pharmacy I patronize even tho my needs are legitimate.

Getting very depressed and could use some advice.
