I have a hard bump (under the skin) on my thumbs knuckle/joint

This answer was rated:

I have a hard bump (under the skin) on my thumbs knuckle/joint - about 8mm diameter and 3mm high in size (when I bend my thumb). Also, the pad of my thumb sometimes tingles. Is the bump maybe pressing a nerve? What might the bump be and what type of doctor would I go to for treatment if needed, a family MD or bone doctor etc.

Thanks,
Rick

Hello!

JACUSTOMER-8vc08ulu- :

Hello

Anthony Bray MD :

From your description it sounds that you may have a ganglion cyst at the affected joint. This is from the issue that covers the joint space and fluid from within the joint. This is likely what is going on.

Anthony Bray MD :

I would recommend that you have this checked by an orthopedic specialist.

JACUSTOMER-8vc08ulu- :

Is it dangerous?

Anthony Bray MD :

It may be that this cyst may cause some nerve impingement and this may be why you have the tingling sensation.

Anthony Bray MD :

No, it is not dangerous.

JACUSTOMER-8vc08ulu- :

Are there different types of orth spec.? Or is that what I look for in the phonebook?

Anthony Bray MD :

You can check to see if the specialist does work on hands. Not all orthopedists do this type of problem. This is not a subspecialist per se but just that some of these specialists will take more of an interest in this area.

JACUSTOMER-8vc08ulu- :

That sounds like the answer I was looking for Thanks!

JACUSTOMER-8vc08ulu- :
