"What Causes Pain in the Back Skin?"

Update Date: 2025-02-15 Source: Network

Back Skin Pain Causes

Back skin pain may be caused by epidermal cysts, herpes zoster, or lumbar dorsal fascia inflammation. All three conditions share the symptom of back skin pain, but it is difficult to determine the specific cause solely based on this symptom. A comprehensive examination at the hospital is required to identify the exact cause based on specific symptoms, followed by targeted treatment.

1. Symptoms of Epidermal Cysts

Epidermal cysts can occur on any part of the skin, but they are more common on the face and upper trunk. The skin lesion appears as a well-defined nodule, and a central pore is clinically visible, representing the hair follicle from which the cyst originates. The cyst diameter ranges from a few millimeters to several centimeters. Tiny, superficial epidermal cysts are called milia. Epidermal cysts are usually asymptomatic, and squeezing them can extrude囊 contents with an unpleasant odor. Rupture of the cyst wall or secondary infection can lead to severe painful inflammatory reactions, which is a common reason for patients to seek medical attention.

2. Symptoms of Herpes Zoster

Before the rash appears, there may be mild fatigue, low fever, anorexia, and other systemic symptoms. The affected skin may feel hot or have neuralgia, with obvious pain sensitivity when touched, lasting for 1 to 3 days, or there may be no prodromal symptoms before the rash appears. The preferred sites are the intercostal nerves, cervical nerves, trigeminal nerves, and lumbosacral nerve innervation areas.

3. Symptoms of Lumbar Dorsal Fascia Inflammation

The main symptoms are diffuse soreness and pain in the lumbar and back regions, especially more pronounced on both sides of the lumbar muscles and above the iliac crest. There may also be muscle stiffness or tension, tenderness when pressed, and palpable cord-like or nodular structures. Inactivity for a long time or excessive activity can both induce pain, and it can flare up due to fatigue and climate changes. The pain is generally severe in the morning, lighter during the day, and aggravates in the evening.
