. Diclofenac sodium (anti-inflammatory painkiller)
This is a non-steroidal anti-inflammatory drug (NSAID).

• It blocks chemicals in the body called prostaglandins (these cause pain and inflammation).
• Result: reduced swelling, pain, and stiffness in the affected area.

• Menthol creates a cooling sensation on the skin.
• This distracts the nerves from pain signals and gives quick, soothing relief.
• It can also slightly improve blood flow to the area.
