Greetings Madam. First of all just be relax. It s a common problem. It s appreciable that you have found out the swelling at an earlier stage, maintaining good eating habits, pass motion everyday, no bleeding during defecation, maintaining height for your weight & even good to hear that there isn t any other systemic problems. Great going!! But since the swelling is getting bigger and giving you discomfort viz., pricking/pain sensation, some serious thing happening inside. Just answer following questions: 1. Have you got any fever? 2. Has the swelling ruptured and reappeared or just increasing in size? & understand that i can t ask more here. It s advisable to go to a doctor and get examined, in order to find out the exact nature of your problem(or any other problem causing you trouble in that area mentioned) & get treated accordingly before it gets complicated . Here you can get only guidance. No doctor will be able to treat unless they see a patient. And coming for home remedy as temporary measure, follow these simple steps: 1. Take cold Shower instead of hot bath. 2. Eat green vegetables viz., salads; oat meal 3. Drink plenty of water viz., minimal 8 glasses/day. 4. Maintain proper Hygiene of genital area viz., Clean the affected area with soap and water. 5. Then if pain in anus, take a SITZ bath(a warm, shallow bath with salt added that cleanses the space between the rectum and genital region) can be used for everyday personal hygiene & also it provide relief from pain or itching in the genital area.You can give a sitz bath in your bathtub. & Finally, Approximately 30-50% of people with an anal abscess(an infection happening inside your existing swelling which rupture) will develop an anal fistula(an abnormal or surgically made passage between a hollow or tubular organ and the body surface, or between two hollow or tubular organs). Around 80% of all anal fistulas develop from an infection already in the anus. Consult your Doctor if you feel uncomfortable in spite of above measure. Hope it helped you.
