Injection fibrosis

Injection fibrosis is a complication of intramuscular injection, resulting in a fibrotic mass at the site of injection. It is often associated with persistent pain and limited function in the affected area.

Causes

Injection fibrosis is caused by repeated intramuscular injections in the same area. This can occur in patients who require frequent injections for conditions such as diabetes or multiple sclerosis. The repeated trauma to the muscle tissue can lead to the formation of a fibrotic mass.

Symptoms

The main symptom of injection fibrosis is a hard, fibrotic mass at the site of injection. This mass can cause discomfort and limit the function of the affected area. Other symptoms can include persistent pain, inflammation, and limited mobility.

Diagnosis

Diagnosis of injection fibrosis is typically made through a physical examination and medical history. The doctor will look for a hard mass at the site of injection and ask about the patient's history of injections. In some cases, an ultrasound or MRI may be used to confirm the diagnosis.

Treatment

Treatment for injection fibrosis typically involves avoiding further injections in the affected area. Physical therapy may be recommended to improve mobility and reduce pain. In severe cases, surgical removal of the fibrotic mass may be necessary.

Prevention

Prevention of injection fibrosis involves rotating the sites of injection and using proper injection techniques. Patients who require frequent injections should be educated about the importance of rotating injection sites to avoid repeated trauma to the same area.
