Thank you for asking on HCM.
If I was your treating physician i will do the following for your pain:
1. Start tab duloxetine
( this is a strong antidepressant having a special feature to relieve body pains).
2. Start tab pregabalin
. It is useful in relieving neuropathic pains in the body.
3. Investigate for other causes of neck and back pain
by doing an X-ray of the neck spine and back.
4. Self CBT or professional talk therapy
I can understand the pain that you are going through and the stressful times you have been through. You can also join social support groups online and start simple muscle relaxation exercises.
I hope you find this helpful.
