Hi welcome to H.C.M.Forum. it is a clear cut case of a hematoma
. cysts usually never bleed.
iadvise you to consult a surgeon for diagnosis, & treatment. you may need to get the colour doppler test or CTscan to evaluate the extent of the swelling in side. the bleeding is also caused repeatedly by hypertension
also if it is not under controle. to be on safe side ristrict salt usage. wishing for smooth recovery.
