What kind of pain? Muscle? Nerve? Pain relief is different for everyone as pain experience is different for everyone. Indicas typically offer good pain relief, but sativas can as well. I'd also look into making RSO. It's kind of the heal all. Reduces inflammation, great pain relief, helps with sleep, anti cancer, etc. As someone mentioned, combining CBD with THC can be a good idea. I'd recommend a full spectrum CBD tincture combined with cannabis. Find a ratio that works. Some people like 1:1 for pain relief. Some like 10:1, again, everyone is different.
