Mucous Cyst on The Fingers: Symptoms & Treatment
A mucous cyst is pretty common. It is medically described as a swelling filled with a liquid that usually appears in the region of the lip or the mouth.
However, for people in the age bracket of fifty to seventy, these blister-like cysts also start to affect the fingers. This is called digital mucous cyst. If you are alarmed by its occurrence, we are here to tell you that it is not such a big deal. Let’s see why.
Anatomy of A Digital Mucous Cyst
This ailment usually affects the joints of the finger, farthest from the knuckle. The mucous cyst is a kind of swelling, in the form of a small, sac-like structure. It is filled with a mixture of fluids commonly found in the human body.
This ganglion is attached by way of a stalk to the distal (the side of the joint closer to the tip of the finger) part of the said joint.
This swelling is what appears in the form of small bumps on fingers. Although most patients report a single bump on the surface, there may be concealed cysts deeper toward the joint.
The reason for the formation of these cysts is a mystery to the medical community, although it has been noticed that the ailment strikes those who suffer from osteoarthritis.
One of the numerous speculations mentions that the wasting away of the connective tissues – a feature common to old age and osteoarthritis – is responsible for the production of free collagen. This collagen accumulates to form little sacs and the fluid from the joint flows inward to fill the cyst.

How to Treat Mucous Cyst?

Surgical Options

After having received postoperative care, doctors normally perform the procedure under a localized anesthetic and take no more than half an hour, the post which, the patient is free to go home.
The affected finger is kept bandaged for a fortnight and the stitches are removed hence. Ideally, if a bone spur is responsible for causing the cysts, it is recommended to get rid of the spur surgically before attacking the cyst, as otherwise there would only be a recurrence.
Along with the spur, the stalk attaching the cyst to the join also has to be removed. Sometimes, the cysts are too close to the skin, in which case the small patch of the skin may also have to go, which can be remedied by way of a skin graft.

Although the surgical route is advised only under extreme scenarios, it reports a high degree of success; some studies suggest that nearly ninety-five percent of the patients report no relapse of the cysts.
Non-Surgical Options
Expedient as it may seem, draining the fluid from inside the cyst- a process called aspiration, which is done by pricking with a needle, is hardly the solution that works in this scenario. So usually, doctors prefer to have the cysts die naturally.
In some cases, however, the mucous cyst may rupture, exposing the underlying joints to all kinds of infectious agents. This needs to be treated by way of antibiotics – either in the topical form or orally. If that does nothing to prevent the infection, surgery is mandatory.
