Skin abscess means accumulation of pus under the skin. It may be in the form of pustules or it may involve a larger area. Diabetic patients have a higher chance to develop an abscess.It may cause severe pain in the affected area. These can be treated gently with homoeopathic medicines which dry off the abscess and there may be no need for a surgery. Body & Mind Homoeopathy. Dr Monty Talwar. Depression, Anxiety disorders.
