Dealing with Occipital Neuralgia: Seeking Advice

Hi I'm new here, I was diagnosed with Occipital Neuralgia last year but have been suffering for over 20 years prior to a diagnoses. I've been seeing a chiropractor for years and that helps to an extent, and I'm on gabapentin which again helps a bit. But I'm still suffering, I've had steroid injections a few times as well, sometimes helped sometimes didn't. Bit hit and miss. Wondering if anyone with the same issue benefits from massage and is there a specialist massage you'd need to have, I obviously don't want it to get any worse. Also how on earth do you sleep with it, I never have a good sleep? Thanks to anyone that replies.
