Lateral Epicondylalgia (Tennis Elbow)
The most common elbow complaint in active adults. Despite the name, this is a tendinopathy of the common extensor tendon on the outside of your elbow, not an inflammation. Think of the tendon as a rope: repetitive use causes individual strands to fray. In adults over 30, the body struggles to repair these micro-tears fast enough, leaving you with disorganized, weakened tissue that hurts with every grip. (PMC, 2014)
| Feels like | Aching or sharp pain on the bony outside of the elbow; weak grip; pain when lifting objects palm-down |
|---|---|
| Worse with | Gripping, turning doorknobs, shaking hands, lifting with palm down, typing/mouse use |
| Better with | Resting the forearm, lifting with palm up (supinated), using a counterforce brace |
| Key insight | This is a degenerative process ("tendinosis"), not an acute inflammation ("tendinitis"). Treatment requires progressive loading to rebuild the tendon, not just rest. (Cleveland Clinic, 2024) |
