But, since yours is close to the 5cm mark, you should have very close follow-up. A
MRI may be the next step to get a better idea of the contents of that cyst. Your doctor may decide to watch and monitor it for a bit or to do surgery to remove it. Since you are in severe pain, I think you need help right away. Do you have an appt. soon? If not, please do call your doctor's office and let them know about your pain level. Make sure they order a MRI and are not just letting this go.
