the nodule on the side of your ring finger can be nodular stage of dupuytrens contracture or it may be trigger finger
which also presents similarly. in trigger finger there is difficulty in flexing and extending the finger and the finger releases like a trigger of pistol. it usually happens in elderly. if you are sure that it is dupuytrens contracture then a single nodule is not a indication of surgery and you need not to worry at this stage unless it progresses (it can). it cannot be melted down as such, for this either intralesional steroid
injections or surgery is required.
