Most exercise-related pain is dull and spreads over a larger area of your arms or legs. This is normal. When it seems to be sharp pain focused in one spot that you can pinpoint with a finger, it may indicate a muscle strain of a tendon inflammation. Popping, clicking, or grinding in the muscles or tendons are signs of strain.
Tendons are pieces of connective tissue that bind your muscles to bones. Like any part of the body, injury or overuse can lead to pain or inflammation in your tendons. This condition is called tendinitis. Biceps tendinitis is most often the result of everyday wear and tear on the muscle. In terms of sports, weightlifting is one of the high risk activities for biceps tendinitis, but this condition is a common sports injury that can happen to pros and amateurs alike.
Your brachial plexus is a network of nerves in your shoulder that branches into five major nerves in each arm. It carries signals from your spinal cord to your arms and hands, allowing you to move your arm, hands, and wrists. Sensory skin nerves are also part of the brachial plexus and allow you to feel temperature and other sensations. There are several types of brachial plexus injuries, with many different causes. They also vary in severity, with some people healing completely on their own and others having permanent damage.
There has been a recent increase in ulnar collateral ligament injuries. These injuries typically occur in overhead athletes and baseball players, but can occur in athletes at all competition levels.
Tennis elbow (lateral epicondylitis) is swelling, inflammation, and subsequent tearing of the tendons in your forearm.These tissues, which attach muscle to bone, can become overtaxed with repetitive use, causing an aching or burning pain that gets worse when you grip or lift something.
