Zerodol TH 4, which contains the active ingredients aceclofenac and thiocolchicoside, can help reduce pain, inflammation, and muscle spasms. While it may provide temporary relief, your symptoms have been progressively worsening and spreading over two months. This persistent pattern suggests the need for a proper medical evaluation rather than just managing symptoms with pain relievers. I highly recommend consulting a healthcare professional to identify the underlying cause of the swelling and receive a safe, tailored treatment plan.
