Next Steps
removing surgically is not at all good solution. when you remove it once from somewhere over the skin it may start somewhere else, n this time it can go deeper the layer of skin, or any organ.....this is natural tendency
Health Tips
instead you can go to any good homoeopathic doctor near you and ask them to treat you. within 6-12 months the recent one's will get dissolved and older one's will take more time obviously.
