I'm going to ask you what I seem to ask every time a post like this appears:
--- > What did your doctor say?
I'm presuming your measurement is in millimeters. That's the only size that would be considered "small."
From what I understand in generalities, size is only one issue in the neurosurgeon's decision whether or not to operate. The location of the tumor, the grade, the total condition of the patient, and the risk analysis of outcomes are all a consideration. Certainly, having symptoms is an issue. It's important to have it determined that the meningioma is the actual cause of the symptoms. Sometimes it's not.

Neurosurgeons are often not big talkers. But your doctor, who is the only one who had seen your MRI and has evaluated you, is the only one who can properly inform you about surgical options. Or other options. Or explain what your treatment plan is. Or if and how your tumor is related to your symptoms.
There are generalities. Yes.

What is regularly done here by patients like you is to get a 2nd opinion. Most of us select a well established tumor- experienced facility. You're posting on one of the best: Mayo Clinic. You can contact them easily even from the forum. Or you can find another one of your choice+ location.
But 2nd opinions by EXPERTS in brain tumors are the way to go in regards to purely expert medical opinions

I hope all goes well for you. You shouldn't have to struggle with so much uncertainty and have symptoms that aren't being addressed or even explained.

I know the burden of your symptoms too.

Seek doctors and others who can offer suggestions at least to help relieve symptoms. Surgery may be a long term answer but there are interventions to help many symptoms.
Keep reaching out.
Prayers and hugs are for you.
Continue checking in on this forum.
Read as much as you can that is in any way related to brain tumors just to familiarize yourself with the broadness of brain tumor experience.

God bless you.
