Pain and Different Types of Pain Killers

Dr Gurmeet Singh Sarla


Pain is an unpleasant sensation that can range from mild, localized discomfort to agony and is quantifiable on various available pain scales. Pain threshold of individuals vary and it is entirely a subjective phenomenon. Analgesic alludes to a prescription that gives relief from torment.  The largest group of over-the-counter painkillers are NSAIDs which do not contain steroids and are used in the treatment of many different kinds of pain, including headaches, dysmenorrhoea, backache and toothache. Acetaminophen (paracetamol) is another very widely used analgesic which also relieves pain and lowers fever but unlike NSAIDs it doesn't reduce inflammation. Opioids are the most effective drugs in the treatment of severe pain but if not used judiciously have serious side effects and dependence. Clove oil, camphor, menthol are extensively used in dentistry as good analgesics. Capsaicin, oil of camphor, Curcumin (turmeric), cod liver oil and green tea have been used as natural/herbal analgesics and anti-inflammatory agents. Therapeutic heat, cryotherapy, ultrasonic therapy and transcutaneous electrical nerve stimulation that use low voltage electric current to relieve pain are effective and safer physical modalities available for treatment of low backache.
