I went to an oesteopath following excruciating neck and arm pain back in November. As he had no idea what was wrong, he was extremely gentle with me and I was to tell him straight away if what he was doing was hurting. (He was only doing intense massaging)
I paid for an MRI a few weeks later, it showed a herniated disc. Luckily the osteopath was sensible. Sounds like your Chiro was far too keen.
As has been said already, you need a diagnosis. Sooner the better. I wish you well.
