Thank you.
Yes, the pain is quite different to what I have been previously experiencing but almost certainly linked to the other problems.
I have psoratic arthritis, spondylosis/itis (can never remember which), facet syndrome and entrapment which previously have resulted in limited movement and caused (relatively) dull pain. This is a sharp and intense pain, quite different. In the past it has been suggested from x-rays that I have spurs on cervical vertebrae but recent x-rays haven't been noted as showing the spurs.
I'll try Diclofenac and see what happens, I just wasn't sure if it would work in this situation.
