I have a bible bump cyst on my right thumb on the outside of the joint from the joint to the finger nail. It is not painful until i go bowling then it is way painful. I have been rolling my thumb with pressure to move the cyst on the top and then it spreads out for a few hours but in the morning it is back as it was before. How do I remove it, slightly cut it open with a razor blade (sanitized) and push out the fluid. Will that make it go away. I had hit it with a hammer but it hurts and does not move it.
