Chronic coccygodynia, persistent tailbone pain aggravated by sitting, requires clinical diagnosis supported by imaging. Identifying causes like coccyx issues or tumors guides treatment from therapies to surgery.
Area of Science:
- Orthopedics
- Pain Management
- Radiology
Background:
- Chronic coccygodynia is defined as tailbone pain lasting over six months, worsened by sitting.
- Diagnosis is primarily clinical but requires imaging to rule out pathologies and understand pain mechanisms.
Purpose of the Study:
- To review the diagnostic and therapeutic approaches for chronic coccygodynia.
- To highlight the role of imaging in identifying causes and guiding treatment.
Main Methods:
- Review of diagnostic imaging techniques including dynamic X-rays, MRI, scintigraphy, and coccygeal ultrasound.
- Discussion of common etiologies such as coccyx hypermobility, rigidity, spicules, trauma, and post-obstetric factors.
Main Results:
- Dynamic X-rays are the reference standard for coccyx examination.
- Coccygeal ultrasound with dynamic maneuver is an emerging, though not fully validated, diagnostic tool.
- Common causes include coccyx abnormalities and trauma.
Conclusions:
- Effective management of chronic coccygodynia involves a stepwise approach.
- Treatment options range from manual therapies and infiltrations to surgery for refractory cases.

Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
