How Effective Is Voltaren Emulgel for Chronic Joint Pain?

I’ve been dealing with chronic joint pain in my knees and lower back for years and recently heard about Voltaren Emulgel. I'm curious to know if it's effective for long-term relief, especially when used consistently. Has anyone with similar chronic issues experienced noticeable improvements? I would love to hear about your dosage Voltaren Emulgel , frequency of application, and how it compares to oral NSAIDs. Any tips or warnings would also be appreciated.
