What could be the cause of pain in the left elbow and forearm?

Pain in the left elbow and forearm has several common causes. One is lateral epicondylitis, also known as tennis elbow. This condition occurs when the muscles and tendons around the outer elbow become overused or injured, causing pain that radiates down the forearm. People who perform repetitive wrist and arm movements often develop this condition. Another cause is cubital tunnel syndrome, which happens when the ulnar nerve near the inner elbow becomes compressed or irritated. This leads to pain along the inner elbow and forearm. Other tendon problems around the elbow can also cause discomfort, typically from strain or inflammation in the tendon tissues. These problems usually develop from repetitive movements, improper technique, or injury.
