The pattern of left-sided excessive sweating with absent sweating on the right side suggests a possible autonomic nervous system disorder. A normal brain MRI is reassuring, but further evaluation is needed to identify the cause. Please consult a neurologist for detailed autonomic examination and consider imaging of the neck/chest (MRI cervical spine or CT chest) and other investigations as advised. Seek urgent care if you develop weakness, drooping of the eyelid, vision changes, or difficulty speaking

Please consult a neurophysician physically.

Sweating strictly on one side of the body — with the opposite side completely dry — is called unilateral hyperhidrosis, and it is a neurological finding that warrants proper investigation. The normal brain MRI is reassuring, but this condition is often not caused by a brain issue — it is typically due to the sympathetic nervous system pathways that control sweating being disrupted somewhere along the spine or peripheral nerves. The distribution you describe (left face, neck, and chest) points toward possible involvement of the cervical or upper thoracic sympathetic chain. This can occur in conditions like Harlequin syndrome (usually benign), a cervical or thoracic spine abnormality, or rarely a lung apex lesion compressing the sympathetic nerves.

Sweating on only one side of the body is called unilateral hyperhidrosis. It is rare and is due to neurological or sympathetic nerve problems. The root cause maybe 1. A spinal cord issue 2. Localized nerve damage. 3. Conditions like Harlequin syndrome or Horner's syndrome. Treatment is: 1. Manage the primary cause. 2. Localized nerve-blocking injections like Botox. 3. Anticholinergic medications like oxybutynin or glycopyrrolate 4. Controlling the specific nerve irritation if the cause is nerve compression, a nerve lesion, or an autonomic disorder.

Consult first with dermatologist asap.
