I have a large boil in my armpit that is full of puss and blood believe it to be cyst but am not sure What could what should do?

It's important to seek medical attention for a boil, especially if it is large and full of pus and blood. A boil is a skin infection caused by bacteria, and it can be dangerous if not treated properly. If you believe it may be a cyst, it's still crucial to have it evaluated by a healthcare professional to determine the cause. Here are some tips on what you can do:

1. Do not attempt to drain or squeeze the boil yourself. This can spread the infection and make it worse.

2. Apply warm compresses to the boil for 20 minutes several times a day. This can help to draw the pus out of the boil and promote healing.

3. Keep the area clean and dry. Wash the boil with soap and water and pat it dry. Avoid using harsh soaps or rubbing the area.

4. Apply an antibiotic ointment to the boil. This can help to prevent the infection from spreading.

5. Take over-the-counter pain relievers, such as ibuprofen or acetaminophen, to relieve pain and inflammation.

6. See a doctor if the boil does not improve after a few days of home treatment, if it becomes larger or more painful, or if you have a fever. The doctor may need to drain the boil, prescribe antibiotics, or recommend other treatments.

It's important to follow the doctor's instructions carefully to ensure proper healing and prevent complications.
