Hi there karen.
Dont worry what seems a magical skin growth in effect is a simple matter of a beingn skin tumor
most likely a 'lipoma' or a 'sebaceous cyst'.
The 'slipping' beneath the finger & disappearance points more to the former.
The treatment is 'masterly inactivity' if not bothering you. If however, for cosmetic reasons you wish to have it removed, do go across to a competent dermatosurgeon or general surgeon
It is a tiny surgery done under local anaesthesia in the outpatient & the cost will be as per the centre but really a minor issue with nothing to wory about.
Hope this has calmed your nerves & given you direction!
Cheers & Good Luck!
