hello, welcome to HCM,
mucous or myxoid cyst
arises from degeneration in the connective tissue
on the top of the last segment of the finger. It may connect with the joint at the end of the finger.
It often causes a groove in the nail, a few millimetres across which extends the length of the nail. The cyst's size may vary. Jelly-like sticky fluid may be expressed from it (sometimes tinged with blood).
1.Squeezing out its contents (make a hole with a sterile needle)
COBAN TAPE DOESNT HELP U IN THIS REGARD.....
but unfortunately, recurrence is more common with any type of treatment method you follow....
