google is alright. Pretty decent if you know how to use it efficently.
Though it is good for feedback from people that have certain problems or just need advice from knowledgable ppl.
Depends on the pain and extent of damage.
I dont get a strong enough opioid for my chronic pains but yeah.
the more documentation on paper about your injury or what not will help tremendously, Eventually lead up to getting whatever you ask
mri's help out a lot for real.
In short, of course they do. Most any chronic pain condition is treated with fentanyl by docs who prefer it to other opioids or where fentanyl is superior to other opioids depending on the patient's circumstances.
