Do not squeeze or prick yourself on the thigh to break the boil as this can spread the bacteria inside the infection. infection to deeper parts of your skin Keep the boil and surrounding skin clean Wash your hands with soap or use an antiseptic before and after touching the boil. Apply warm compresses regularly during the day, this will help the pimples to dissolve. The American Academy of Dermatology (AAD) recommends applying warm compresses for 10 to 15 minutes, 3 to 4 times a day until the boil heals. You can apply warmth by dipping a clean washcloth in hot water and making sure the water is not too hot. If the boil is draining or in an area prone to friction, you should cover it with a clean bandage. This can limit irritation. It's hard to avoid friction in the inner thighs, but you can wear underwear and loose clothing to avoid aggravating boils. The AAD also recommends ibuprofen or acetaminophen for pain from boils. Over-the-counter antibiotics and antiseptic creams and liquids can be gently applied. Periodic replacement of personal hygiene products can cause cuts and scrapes, especially razor blades. For chronic or severe infections, clean any products that come into contact with your body daily. 5.2 Clinic treatment In many cases, you can treat boils at home. If home treatment doesn't work, your doctor may prescribe other treatments.
For boils that are large and do not go away on their own, the doctor can perform the procedure in the clinic. It's called incision and drainage or what many people say, thigh prick. Your doctor will make a small incision in the pimple to drain the pus and also usually send a sample of pus to a lab for testing. Lab technicians can help identify the specific bacteria causing the infection, which can help your doctor decide which antibiotic is best to treat if needed. Depending on the size, location, and other symptoms of the boil, draining the pus may be enough to cure the infection. Your doctor may prescribe antibiotics by mouth. More serious infections may require hospitalization and intravenous antibiotics. For boils on the thighs that recur frequently or if you develop complications, your doctor may refer you to a dermatologist. Or they may refer you to an infectious disease specialist. For infections and larger abscesses, your doctor may order an ultrasound of the boil area.
