Hello
As your mother were taking
prednisolone 5 mg , increased dose up to 15 mg a day .
The side effects were kidneys and breathing problems . Beside there is accumulation of fluid in body , with weight gain , reabsorption of calcium from bone etc.
But your mother is not taking steroid just now and that from last 2 weeks .
Now your mother is having fever , chills , pain in joints and muscles, dry moth.
I want to tell you that all these symptoms are not due to withdrawal of prednisolone .
These symptoms may be due to
RHEUMATOID ARTHRITIS .
Your mother is not taking any medicine for R A , that is the reason that she is facing such type of symptoms .
2nd reason of such symptoms may be due to
Kidney infection . Diagnosis can be confirmed by urine examination with
ultrasound of both kidneys.
3rd reason of course may be malaria , so get in blood for malarial parasite.
In my opinion just
consult a Rheumatologist and get his opinion.
Good luck.
