Hi I am Chat Doctor. .  In my opinion that could be cervical radiating pain due to spinal disc herniation that may cause such neuropathic pain. Try to avoid heavy lifting, over using or vigorous movements , physiotherapy, yoga, hot massages with topical gels, NSAIDs painkillers like Advil tabs when needed, B12 vitamin supplementation, muscle relaxants will be helpful. If pain persists I recommend further imaging by MRI scan on your spine for proper evaluation and management.
