Arthritis: Types, Symptoms, Causes, and Treatment

"Arthritis" is an umbrella term covering more than 100 different joint conditions — how the main types differ, how they're diagnosed, and when joint pain needs evaluation.

Knee Osteoarthritis Treatment: From Exercise to Knee Replacement

Knee osteoarthritis can't be reversed, but a range of treatments — starting with weight management and exercise — can meaningfully reduce pain and preserve function for years before surgery is needed.

Knee Osteoarthritis

Knee osteoarthritis is the gradual wearing down of the cartilage that cushions the knee joint — the most common cause of chronic knee pain as people age.

Treatment for Sciatica

Most sciatica resolves within weeks to a few months without surgery — here's the typical treatment progression and when more advanced options are considered.

Symptoms of Sciatica

Sciatica has a distinctive symptom pattern that follows the nerve's path — here's what to expect and the specific signs that mean it needs urgent attention.

Sciatica

Sciatica is nerve pain, not just back pain — it radiates along a specific path from the lower back down the leg, and usually improves without surgery.

Food Poisoning

Food poisoning usually strikes within hours of eating contaminated food and clears up on its own within a few days — here's how to spot it, treat it, and know when it's more serious.

Gastroenteritis

Often called the 'stomach flu,' gastroenteritis is usually viral, highly contagious, and resolves on its own — the main risk to manage is dehydration, not the infection itself.

COVID-19

COVID-19 today looks different than it did in 2020 — for most vaccinated, healthy people it's a manageable illness, but knowing current symptoms, contagious periods, and risk factors still matters.

RSV (Respiratory Syncytial Virus)

RSV causes mild cold-like symptoms in most people but can be genuinely serious for infants and older adults — here's how to recognize the difference.

Pneumonia

Pneumonia can range from a manageable illness treated at home to a genuine medical emergency, especially for young children, older adults, and people with weakened immune systems.

Bronchitis

A lingering cough after a cold is often acute bronchitis — usually viral, not needing antibiotics, but sometimes confused with pneumonia when symptoms are severe.

Ear Infection

Ear infections are especially common in young children and usually improve within a few days — here's what causes them and when antibiotics or a doctor's visit are actually needed.

Sinusitis

Facial pressure, thick nasal discharge, and a cold that won't quit are the hallmarks of sinusitis — here's how to tell it apart from a lingering cold and what actually helps.

Tonsillitis

Tonsillitis causes a sore throat plus visibly swollen, often white-coated tonsils — usually viral, but frequent recurrence can raise the question of removing the tonsils altogether.

Common Cold

The common cold is the most frequent human illness, usually mild and self-limited — here's what to expect, how to feel better faster, and when it might be something more.

Influenza (Flu)

The flu comes on faster and hits harder than a common cold, and can be genuinely dangerous for some groups — here's how to recognize it, treat it, and know when it needs medical attention.

Fast Heart Rate: Causes, Symptoms, and When to Seek Medical Care

A racing heart is often a normal reaction to exercise, stress, or caffeine — but persistent or unexplained tachycardia can point to an underlying condition worth checking.

Shortness of Breath: Causes

Shortness of breath ranges from an expected response to exertion to a sign of a serious heart or lung condition — here's how the causes differ and when it's an emergency.

Causes of Heart Palpitations

That fluttering, pounding, or skipped-beat feeling is usually harmless and tied to everyday triggers — but a few accompanying signs mean it's worth getting checked.
