What Should I Do for Muscle Swelling?
The causes of muscle swelling generally fall into two categories: one is aseptic inflammation of the muscle due to various factors, and the other is localized muscular infection caused by pyogenic bacteria; thus, their respective treatment approaches differ.

For the former (aseptic inflammation), treatment typically involves oral nonsteroidal anti-inflammatory drugs (NSAIDs), such as aceclofenac, diclofenac, or celecoxib. Alternatively, topical application of diclofenac gel (e.g., Voltaren Emulgel) or herbal preparations with blood-activating and stasis-resolving properties may be used to enhance local circulation. Local heat therapy may also be beneficial. In contrast, muscle swelling resulting from pyogenic bacterial infection is generally managed with early, adequate, and targeted antibiotic therapy based on pathogen sensitivity.
