Is It Safe To Take Etrobax For Osteoarthritis And Tingling Of Hand And Feet?

Along with osteoarthritis, my wife has acute pain in her hands and feet with tingling sensations. Dr. prescribed etrobax 120 for 5 days and then replaced the med with carnisure 500 for 15 days, which is continuing without much relief. She was previously taking diacerein 50 mg and sodium alendronate tabs with not much resutls. Pl. advice. My wife is aged 56 yrs, medium built (54 kgs).
