she is definitely suffering a lot , i understand from your description
the consumption of prednisolone
for her pains has definitely worsened her condition.
so it is better that she takes non steroidal analgesics along with calcium and antacids for immediate and temporary relief.
better she gets her complete hemogram done to confirm or rule out anemia
she needs more of reassurance and psychological support to face her problem more couragiously
with so many problems she needs specialist consultation. better persuade her to accept for consultation
hope i have answered most of your querrys. please feel free to ask me further questions if you desire
