Fasciitis – Causes, Symptoms and Treatment
Fasciitis is an inflammation of the fascia, the connective tissue that surrounds muscles and organs. It can be acute or chronic and affect various parts of the body.

Fasciitis is an inflammation of the fascia, the connective tissue that surrounds muscles and organs. It can be acute or chronic and affect various parts of the body.
What is Fasciitis?
Fasciitis refers to the inflammation of the fascia – the fibrous connective tissue that surrounds, supports, and separates muscles, organs, and other structures throughout the body. Fascia plays a critical role in movement, force transmission, and the protection of internal structures. When fascia becomes inflamed, it can cause significant pain and functional impairment. Fasciitis can affect virtually any region of the body, but it most commonly involves the sole of the foot (plantar fasciitis) or the pelvic area.
Types of Fasciitis
Plantar Fasciitis
Plantar fasciitis is the most common form. It affects the plantar fascia on the underside of the foot and typically causes sharp, stabbing heel pain, especially with the first steps in the morning.
Necrotizing Fasciitis
Necrotizing fasciitis is a rare but life-threatening bacterial infection in which inflammation spreads rapidly along the fascial planes, causing severe tissue destruction. It requires immediate emergency medical treatment.
Eosinophilic Fasciitis
Eosinophilic fasciitis (also known as Shulman syndrome) is a rare connective tissue disorder characterized by thickening and hardening of the fascia, accompanied by elevated eosinophils in the blood.
Plantar and Palmar Fibromatosis
These special forms affect the fascia of the sole of the foot and the palm of the hand, respectively, and are characterized by nodular thickening of the connective tissue.
Causes
The causes of fasciitis vary depending on the specific type:
- Overuse and mechanical stress: A common cause of plantar fasciitis, for example from prolonged standing, running, or improper footwear.
- Bacterial infections: The main cause of necrotizing fasciitis, most often caused by Group A Streptococcus or other pathogens.
- Autoimmune reactions: The underlying cause of eosinophilic fasciitis, often triggered by intense physical activity or without a clear cause.
- Foot deformities: High arches or flat feet can predispose individuals to plantar fasciitis.
- Obesity: Increased pressure on the sole of the foot raises the risk of plantar fasciitis.
Symptoms
Symptoms vary depending on the type of fasciitis:
- Sharp or burning pain in the affected area
- Morning stiffness and start-up pain (especially with plantar fasciitis)
- Swelling, redness, and warmth of the tissue
- In necrotizing fasciitis: rapidly spreading redness, blistering, tissue destruction, and high fever
- Hardening and thickening of connective tissue (in eosinophilic fasciitis)
- Restricted mobility of the affected body region
Diagnosis
The diagnosis of fasciitis is typically established through a combination of:
- Clinical examination: Assessment of tenderness on palpation, limited range of motion, and visual inspection of the affected region.
- Imaging: Ultrasound or MRI (magnetic resonance imaging) to visualize thickening or signs of inflammation in the fascia.
- Laboratory tests: Complete blood count, inflammatory markers (CRP, ESR), and eosinophil count when eosinophilic fasciitis is suspected.
- Tissue biopsy: Used in unclear cases or when necrotizing fasciitis is suspected.
Treatment
Conservative Therapy
For the common plantar fasciitis, conservative measures are the first line of treatment:
- Rest and offloading of the affected area
- Stretching and strengthening exercises for the calf muscles and plantar fascia
- Orthotic insoles or supportive footwear
- Physiotherapy and extracorporeal shockwave therapy
- Anti-inflammatory medications (NSAIDs) such as ibuprofen
- Local corticosteroid injections
Treatment of Necrotizing Fasciitis
Necrotizing fasciitis is a medical emergency. Treatment involves:
- Immediate surgical removal of infected tissue (debridement)
- High-dose intravenous antibiotic therapy
- Intensive care monitoring and supportive treatment
Treatment of Eosinophilic Fasciitis
This rare form is typically treated with corticosteroids (e.g., prednisone) to suppress the overactive immune response. Immunosuppressive agents may also be used in refractory cases.
Prognosis and Prevention
The prognosis depends strongly on the type of fasciitis. Plantar fasciitis resolves completely with conservative treatment in most cases. Preventive measures include wearing appropriate footwear, regular stretching, avoiding overuse, and addressing structural foot deformities. Necrotizing fasciitis carries a high mortality rate if not recognized and treated promptly, even with modern medical care.
