What causes soreness and pain in the left forearm?
Recently, my left forearm has been sore and painful, especially after lifting heavy objects or maintaining the same posture for a prolonged period, with the discomfort becoming more pronounced. I wonder if this might be caused by overexertion? What exactly is causing the soreness in my left forearm?

Left forearm soreness is a common symptom that may be caused by various factors. The following are some possible causes:
1. Muscle strain: Overexertion or a sudden increase in physical activity can lead to muscle strain, causing lactic acid buildup and pain.
2. Muscle or tendon injury: Overuse, repetitive movements, or sudden strenuous activity can cause strains in the muscles or tendons, resulting in soreness.
3. Nerve compression: For example, carpal tunnel syndrome is caused by compression of the median nerve at the wrist, leading to pain and numbness in the hand and forearm.
4. Trauma: Injury to soft tissues or bones may result in left forearm pain.
5. Circulatory problems: Conditions such as Raynaud's disease or Raynaud's phenomenon may cause blood vessel constriction in the extremities, leading to pain.
6. Cardiac issues: Although less common, heart conditions such as angina or myocardial infarction can sometimes present as pain in the left arm.
7. Metabolic diseases: For example, nerve damage caused by diabetes may also lead to limb pain.
If the pain persists or is accompanied by severe symptoms such as swelling or redness, it is recommended to seek medical attention immediately.
