My grandmas suffering from chronic pain, she has mult things wrong and wont take no opiate meds do to stomach disorders, is there any that wont effect?

Other than opiates: Opiates are not the best way to treat chronic pain. There are a number of other agents that might help, including gabapentin, nortriptyline among those. She should see a pain specialist or a neurologist. Depending on what is causing the pain, there may be more focused, localized treatments as well.

Opiate pain: All will cause symptoms so use the smallest dose possible to see if she can tolerate them if she can't tolerate consider different pain meds or treat the side effects.

See Pain Specialist: The only way to give you the best advice for your grandma, you should ask her to schedule an appt with a qualified trained pain management specialist. There are multiple treatment options but each are individual to the patient so it's hard to give basic advice here.

Yes!: There are lots of different types of pain medications. I recommend seeing a pain doctor.
