What causes radiating pain from my neck to my right hand and foot with burning sensations?

Radiating pain from the neck to the right hand and foot, along with burning sensations, could indicate a problem involving the nerves. One possible cause is cervical radiculopathy, which happens when a nerve in your neck is compressed or irritated, often due to a herniated disc, spinal stenosis, or degenerative changes in the cervical spine. This can cause pain radiating along the nerve path, including into the arm and occasionally into the leg if multiple overlapping issues exist. Though the foot involvement is less common in cervical issues, it’s possible if there are other underlying conditions. It’s important to consider alternative causes such as thoracic outlet syndrome, which can compress nerves going to the arm, but involvement of the foot suggests looking beyond this. Another possibility is peripheral neuropathy impacting both the arm and leg, although this is less likely to have an origin just in the neck region alone. Conditions like multiple sclerosis or a brain lesion could theoretically also cause unilateral limb discomfort, though these scenarios are less typical. The fact that you’re experiencing burning sensations indicates nerve involvement which might require prompt investigation. I would strongly recommend seeing a healthcare provider as soon as possible. They might perform a detailed neurological exam and suggest imaging tests like an MRI, or CT scan to focus on potential neck or brain-related issues. Depending on the findings, treatments vary from physical therapy and medications to manage pain and inflammation, to more advanced interventions if spinal or nerve root compression is diagnosed. Until then, trying to maintain good posture and avoiding activities that exacerbate your symptoms might help a little. However, given your symptoms, don’t delay in getting a thorough evaluation.
