AMBULATORY CARE:

Signs and symptoms of a ganglion cyst:
- A round, firm lump
- A lump that changes size and may disappear or reappear
- Numbness, swelling, or muscle weakness around the joint where you have the cyst
- Pain in a joint that has the cyst
Call your doctor or orthopedist if:
- You continue to have pain, even after treatment.
- Your cyst returns or gets larger.
- Your limb that has the cyst gets weak, numb, stiff, or unstable.
- You have questions or concerns about your condition or care.
Treatment:
A ganglion cyst will usually go away on its own. You may need any of the following:
- Steroid medicine may be injected into the cyst to decrease inflammation.
- Aspiration may be done to drain the cyst with a needle.
- Surgery may be needed to remove the cyst.
Manage a ganglion cyst:
- Do not try to pop or break the cyst. This can cause tissue damage and the cyst may return.
- Go to hand therapy, if needed. A hand therapist teaches you exercises to help improve movement and strength, and to decrease pain.
- Wear a splint as directed to support and protect the joint that has the cyst. This will limit movement and help your cyst get smaller.
Follow up with your doctor or orthopedist as directed:
