Yes, Dr. Ortho Pain Relief Oil can produce a mild heating or warming sensation on the skin after application due to ingredients such as menthol, camphor, methyl salicylate, and turpentine oil. This warming effect increases blood flow to the affected area and helps distract the brain from underlying muscle or joint pain. It is important to apply the oil gently without rubbing too hard and to avoid using a heating pad or tight bandages over the treated area to prevent excessive irritation or skin burns.
