from the length of ur question I understand ur concerns. the fluid build up may be related to the prednisolone
or due to stopping rx of hypertension
, there may be other reasons too. follow ur dr's advice because a physical checkup is essential for ur condition. An ayurvedic liquid preparation named Punarnavadyarishtha is used empirically to treat fluid collection of unknown cause and has rarely shown untoward effects. to find the cause see ur doctor/specialist he advises.
