Your doctor used a needle or a small tube (catheter) to drain the cyst. Then your doctor injected a chemical (sclerosant) into the cyst. The chemical damaged the cyst to help keep it from returning.

You may have pain, bruising, or soreness where the doctor put the needle or catheter into your skin. This usually gets better after a day or two.

You should be able to go home the same day. You can go back to work or your normal activities as soon as you feel up to it. But avoid strenuous activity until your doctor says it’s okay.

You may have follow-up imaging tests in a few months to check on the cyst. In some cases, a cyst returns. If this happens, you may need to repeat the procedure.

• Rest when you feel tired. Getting enough sleep will help you recover.
• You can do your normal activities when it feels okay to do so.
• Try to do low-impact physical activity each day. This includes walking and bicycle riding.
• Avoid strenuous activities, such as jogging, weight lifting, or aerobic exercise, until your doctor says it is okay.
• You may shower 48 hours after the procedure. Don't swim or take a bath until your doctor tells you it is okay.

• Your doctor will tell you if and when you can restart your medicines. Your doctor will also give you instructions about taking any new medicines.
• If you stopped taking aspirin or some other blood thinner, your doctor will tell you when to start taking it again.
• Ask your doctor if you can take an over-the-counter pain medicine, such as acetaminophen (Tylenol), ibuprofen (Advil, Motrin), or naproxen (Aleve). Be safe with medicines. Read and follow all instructions on the label.
• Do not take two or more pain medicines at the same time unless the doctor told you to. Many pain medicines have acetaminophen, which is Tylenol. Too much acetaminophen (Tylenol) can be harmful.
