Common causes, standard treatments, and their limits
Tennis elbow (lateral epicondylitis) is chronic inflammation of the tendons on the outer elbow caused by repetitive use and accumulated micro-injuries. Despite the name, most patients don't play tennis. It is common among people whose work or daily routines involve repeated wrist and forearm movements—office workers using a mouse and keyboard for long hours, chefs, homemakers (wringing towels, carrying heavy items), carpenters, and manual laborers.
The root cause is repeated micro-injury to the tendon. If you return to the same movements as soon as the pain eases (the same mouse posture, the same lifting technique), the tendon is stressed again before it has fully healed, so it easily recurs and may become harder to heal over time. A few days of rest is often not enough for real tendon repair.
Most patients improve with these measures combined with movement changes. If pain still recurs or interferes with daily life after a reasonable period, other approaches may be needed.
For chronic, recurring tennis elbow that has not responded well to standard treatment, transcatheter arterial microembolization (TAME) is one option to evaluate. A catheter delivers an embolic agent into abnormal small vessels near the painful area to reduce inflammation and pain signaling, without hospital admission.
