What causes stomach pain when doing push-ups?

       Abdominal pain during push-ups may result from either physiological causes or pathological conditions such as muscle injury or myofasciitis.

　　I. Physiological Causes

　　Prolonged performance of push-ups can lead to excessive lactic acid production, which accumulates in the abdominal muscles and stimulates surrounding tissues, causing abdominal pain. This is generally a physiological phenomenon that does not require specific treatment and typically resolves gradually with rest.

        II. Pathological Causes

　　1. Muscle Injury

　　Incorrect form during push-ups may cause tearing injuries to abdominal muscle fibers, resulting in localized pain accompanied by tenderness upon pressure and restricted movement. In such cases, cold compresses—using a towel wrapped around ice—can help constrict blood vessels and reduce pain. Additionally, topical medications for reducing swelling and relieving pain, such as diclofenac diethylamine gel or compound ibuprofen gel, may be used under medical guidance.

　　2. Myofasciitis

　　Long-term improper technique during push-ups may overstretch the muscular fascia, leading to aseptic inflammation. This inflammatory response irritates surrounding tissues, causing symptoms such as abdominal pain and swelling. Under medical supervision, nonsteroidal anti-inflammatory drugs (NSAIDs) like sodium diclofenac sustained-release capsules or indomethacin capsules may be taken orally.

　　Additionally, gastrointestinal spasms may also cause abdominal pain during push-ups. If symptoms persist without improvement, prompt medical evaluation and treatment are recommended.
