Two people walk into my clinic on the same morning with the same complaint: "Doctor, my knee hurts when I bend it." One is a 19-year-old college footballer. The other is a 61-year-old retired teacher who struggles to sit down for puja. (Neither is a real patient, but both will sound familiar.) Same words, very different causes, and very different treatments. Pain on bending the knee is one of the most common reasons people see an orthopaedic doctor. Where the pain is, how it started and what makes it worse usually point to the answer. Here is a simple guide. First, where exactly does it hurt? Front of the knee (around or behind the kneecap): patellofemoral pain, chondromalacia patellae, patellar tendinitis, early arthritis of the kneecap joint Inner side: medial meniscus tear, medial osteoarthritis, pes anserine bursitis, medial ligament sprain Outer side: lateral meniscus tear, iliotibial band syndrome (common in runners) Back of the knee: Baker's cyst, hams...

A 45-year-old shopkeeper. Let us call him Prakash. He is not a real patient of mine, but I meet someone like him every week. He slipped on a wet step and broke the bone just above his wrist. The plaster went on in the emergency room. Two weeks later he is back in my OPD, frustrated. "Doctor, it still hurts. When will the bone join? And can I do something to make it heal faster?" Those are good questions. The answer starts with understanding what is actually happening inside the plaster. A broken bone does not simply "stick" back together. It rebuilds itself, in stages, over weeks and months. The four stages of fracture healing: blood clot, soft callus, hard callus and remodelling 1. Clot Days 0–5 swelling, bruising 2. Soft callus Weeks 1–3 soft bridge forms 3. Hard callus Weeks 3–12 joins on X-ray 4. Remodelling Months–years reshaped, strong The four overlapping stages of fracture healing in an adult. Timings vary with age...

A 48-year-old tailor. Let us call him Bijay. He is not a real patient of mine, but you may recognise him. For months his thumb, index and middle fingers have been tingling. It is worst at night. He wakes up at 3 a.m., shakes his hand hard, and the "pins and needles" slowly fade. Lately he has started dropping buttons and finds it hard to thread a needle, the very skill his livelihood depends on. His question is simple: "Doctor, is this a nerve problem, and will I need an operation?" It is very likely carpal tunnel syndrome , one of the most common nerve problems of the hand. The good news: when it is caught early, most people do well without surgery, and when surgery is needed, results are usually excellent. What is the carpal tunnel? At the front of your wrist is a narrow passage formed by the small wrist bones below and a tough band (the transverse carpal ligament) on top. Through this tunnel run nine finger tendons and one important nerve, the median nerve ...

A 58-year-old shopkeeper. Let us call him Ramesh. He is not a real patient of mine, but I see his situation often. He comes to the clinic with severe knee arthritis. The nurse checks his blood pressure: 168/96. He is surprised. "My BP is always normal at home!" He has also been taking painkiller tablets from the chemist twice a day for months. He asks: "Doctor, can my knee pain raise my blood pressure?" The answer is yes, in more than one way. And the painkillers he has been taking may be adding to the problem. Two ways pain can raise blood pressure: the body's stress response, and painkillers such as NSAIDs that cause salt and water retention Pain Stress hormones, faster heart Painkillers (NSAIDs) Salt and water retention Blood pressure ↑ treated with Check BP if you take painkillers often or have long-standing pain Pain itself and some painkillers can both push blood pressure up.
