chronic pain
"I have a spinal cord injury. I have been on 10/325 for over 2 years now.  Certain brands work better than others.  Generics don't contain the exact same recipe as each one.  So far I have experienced 3 different ones.

Amnea marked with IP204 are by far the best pain relief ever.
Endo which are yellow (and I don't have my old bottle) are worthless for pain relief, these gave me the runs majorly.
Mallinkrt Pharm is the new ones I just got and they are not taking the edge off the pain and giving me horrid constipation.

Unfortunately, if you are a pain patient you are labelled as an addict so telling your doctor that the pill doesn't work is worthless. Ask the pharmacist before what kind they have and let them know what ones work for you!"
