Experiencing tender spots on your head can be concerning, but it’s a common sensation with many underlying causes, most of which are not serious. Understanding these reasons can help demystify scalp tenderness.
Scalp Conditions and Irritations
Dermatological issues directly affecting the scalp can lead to tenderness, often stemming from inflammation or skin damage. Seborrheic dermatitis, or dandruff, causes red, itchy, and flaky patches on the scalp. Scratching can worsen symptoms, leading to sores and infections that increase tenderness.
Psoriasis, an autoimmune condition, can also cause thick, scaly, discolored plaques on the scalp that may be itchy or painful. These plaques can vary in size and may cover the entire scalp, sometimes extending to the hairline, forehead, and behind the ears. Folliculitis, an inflammation or infection of the hair follicles, presents as red, swollen, and tender bumps, which can be itchy, painful, or pus-filled. Contact dermatitis results from an allergic reaction or irritation from substances like hair dyes, fragrances, or hair products, causing a painful or itchy rash with redness, blisters, or even hardened skin sections.
Headaches and Muscle Tension
Various types of headaches and muscle tension can manifest as tender spots on the head, often due to heightened sensitivity in the scalp and surrounding muscles. Tension headaches, the most common type, cause a dull, aching pain or tightness across the forehead, sides, and back of the head. This discomfort often extends to the scalp, neck, and shoulder muscles, which may feel sore.
Migraines, distinct from tension headaches, can also cause increased sensitivity to touch on the scalp, known as allodynia. During a migraine, even non-painful stimuli like brushing hair or resting the head can cause significant pain due to hypersensitive nerve endings.
Referred pain from muscle tension in the neck, shoulders, and jaw can further contribute to head tenderness. Temporomandibular joint (TMJ) disorders, affecting the jaw joint and chewing muscles, can cause pain that radiates to the temples, cheeks, ears, and even the forehead or back of the head. This pain can be a dull ache or pressure and may worsen with jaw movements like chewing, talking, or yawning. Trigger points, small hypersensitive spots in soft tissues, can form from repeated stress on jaw, neck, and face muscles, leading to pain in other areas of the head.
Nerve-Related Pain
Specific nerves can be the primary source of tenderness on the head, leading to distinct pain patterns. Occipital neuralgia is a condition characterized by irritation or injury to the occipital nerves, which extend from the upper spinal cord through the neck and into the scalp. This irritation can cause sharp, shooting, or electric shock-like pain, often originating at the base of the head and radiating to the scalp, sometimes behind one or both eyes.
The pain can be aching, burning, or throbbing, and even light touch, such as brushing hair or resting the head, can trigger an episode. While symptoms can be similar to migraines, occipital neuralgia does not involve nausea or severe light sensitivity.
Other Contributing Factors
Beyond common scalp conditions, headaches, and nerve issues, several other distinct factors can cause head tenderness. Minor trauma or injury, such as a bump, bruise, or small cut, can result in localized pain and soreness. Even prolonged pressure from tight headwear or hairstyles like braids and ponytails can irritate the scalp, leading to tenderness, redness, and sometimes even localized hair thinning. Sunburn on the scalp can also cause tenderness, redness, and flaking, similar to sunburn on other parts of the body.
Infections can also contribute to scalp tenderness. Cellulitis, a bacterial skin infection, can cause painful lumps, abscesses, and swelling on the scalp. Shingles, caused by the reactivation of the varicella-zoster virus, can manifest as a painful, blistering rash on the scalp, often preceded by burning, tingling, or sharp pain. This rash appears on one side of the head, following nerve pathways.
Sinus issues can also lead to referred pain and tenderness in the head, particularly around the forehead, cheekbones, and behind the bridge of the nose. When sinuses become inflamed or blocked, often due to infections or allergies, pressure can build up, causing a deep, constant pain that may radiate to the scalp, temples, and even the upper jaw and teeth. This pressure can worsen with sudden head movements or straining.
When to Seek Medical Advice
While many instances of head tenderness are not serious and may resolve with home care, certain warning signs indicate the need for professional medical evaluation. You should consult a healthcare provider if the tenderness is severe, comes on suddenly, or is accompanied by other concerning symptoms. These symptoms include fever, a stiff neck, changes in vision, weakness, numbness, or confusion.
Immediate medical attention is also advised if the tenderness results from a head injury and the pain worsens, or if you experience slurred speech, balance problems, or memory loss. If scalp soreness persists for more than a few days, worsens despite home remedies, or is accompanied by visible signs like unusual bumps, rashes, or persistent hair loss, seek a diagnosis from a doctor or dermatologist.
