welcome to health care majic
my name is Dr Ehsan ullah
I have been through your concern regarding the lump in the palm ...
Palmer lumps can be of different origin depending upon the
-onset /duration
-features of the lump
like
soft,firm , hard
mobility
consistency
fluctuation etc
one of the common condition which exists on Palmer aspect of the Hand is
Dupuytren's Contracture
other pathological conditions
include
cysts
abscess
lipomas which are benign fat collection
ganglion
and
off course
callus which results from repeated pressure on your hand mostly due to unusual work with tools
now
how to manage ...
your GP will access the nature of the lump and decide whether you need
conservative treatment
or
surgical assessment and management
then you will have to follow the directions and treatment accordingly
hope this answer covers your question
do let me know if anything still now clear
regards
Dr Ehsan
