Thank you very much for the useful information Julie.
You next steps should be;
Strong pain relieving medications such as tramadol, hydrocodone, oxycodone either alone or in combination with conventional NSAID's (like ibuprofen) and paracetamol.
Addition of Nerve soothers (like gabapentin or pregabalin) in your treatment to control the painful neuropathic symptoms such as pins and needles, tingling or burning.
Spinal cervical epidural injections for pain control.
Spinal nerve block injections for pain control.
Even you can also try TENS (transcutaneous electrical nerve stimulation) as well as accupuncture from a certified acupuncturist (many people get relief from this).
And if all these measures fail, then surgery will be the option (but this is usually not required in majority of the cases since most people do well with the treatment options i have mentioned).
You can discuss these with your doctor, get a referral to spinal surgeon for these procedures, or a pain clinic in your area.
Also do discuss about getting strong pain medications as well as nerve soothers i mentioned; while continuing with physiotherapy.
Goodluck and Get well soon.
