- Tendonitis: Tendonitis describes the swelling of ligaments, the fibrous cells that attach muscles to bones. It generally triggers pain and also tenderness around the affected joint.
- Bursitis: Bursitis is the swelling of bursae, tiny fluid-filled sacs that support the joints. It usually takes place due to repetitive motions or extended stress on a joint, leading to pain as well as swelling.
