[20F] Experiencing frequent urination without other symptoms

Frequent Urination

Differential diagnosis

• Given the patient's increased fluid intake, the most likely diagnosis is polydipsia (R63.1).
• Other possibilities include urinary tract infection (N39.0), diabetes mellitus (E10-E14), and diabetes insipidus (E23.2).

Plan

Perform a urinalysis to rule out infection and assess for glucose and specific gravity. If the urinalysis is normal, consider a trial of fluid restriction to see if symptoms improve. If symptoms persist, consider further testing such as a fasting blood glucose test or HbA1c to rule out diabetes mellitus.

Tailbone Tightness

Differential diagnosis

• The most likely diagnosis given the chronicity and intermittent nature of the symptoms is coccydynia (M53.3).
• Other possibilities include musculoskeletal strain (M62.838), sacrococcygeal disorder (M53.3), and referred pain from lumbar spine (M54.5).

Plan

Perform a physical examination focusing on the lumbar spine, sacrum, and coccyx. Consider ordering imaging studies such as X-ray or MRI to rule out structural abnormalities. Recommend conservative management strategies such as use of a coccyx cushion, physical therapy, and non-steroidal anti-inflammatory drugs (NSAIDs) for pain relief. If symptoms persist, consider referral to a specialist for further evaluation and treatment.
