In a case of a fingercyst is medical treatment always necessary?
No! Fingercysts (mucous cysts) are in many cases harmful. As long as the skin – overlying the cyst – is not very thin, it is sufficient to observe the fingercyst.
Sometimes a digital cyst resolve spontaneously
In which cases is a medical treatment necessary?
Sometime a fingercyst will rupture!
If a mucous cyst rupture, a path directly into the fingerjoint beneath the cyst is created! In such a case, bacteria from the skin could enter the joint and can cause serious infection inside the joint.

This does not often happen. However if it occurs… this is a serious complication which requires rapid medical treatment.
Serve cases requires oral antibiotics and often surgery.
Therefore you should never perforate a mucous cyst with a needle from the household!
What should I do, if my fingercyst rupture during work?
In such case you will see a clear jelly-like content empties from your fingercyst. Don’t touch the ruptured cyst with an other finger and particularly not with your tongue. Cover the fingercyst with a sterile plaster.

A treatment (surgical or non surgical) should be considered, if:
you feel significant pain,
you see a groove in the nail,
the skin over the digital cyst is considerably thinned ( the skin is ready to rupture)
the cyst ruptured once or serveral times by trivial injuries
