I know a few people who've had these cysts and all have been helped with medication and injections in the short term. The problem is the cysts can come back. It's worth trying the conservative management approach IMO. Btw, I'd also try and find a chiropractor with a special interest in neurology. They have a different approach to normal chiros.
Also, I don't believe the cysts are as uncommon as you may have read. Cysts themselves are quite common but they are very undereported.
