Hello dear
Welcome to Health care magic family .
I have evaluated your query thoroughly .
@ Though RA is ruled out there are other types of
arthritis as osteoarthitis
age related articular surface erosion , chondroid deposition , loose body
inside the joint spaces , low calcium ,
vitamin D3 levels all are responsible
for her agony .
@
Analgesic spray , certain medications , vitamin D3, B 12 and other
supportive care are only things we can offer her along with praying to
God that she suffers less .
Hope this will help you definitely .
Feel free to ask any future health related query anytime .
Thanks for evaluating my answer thoroughly .
Regards dear take care of her .
