Your mother is signified with Ju in its own sign, not so bad. Ju is hot and moist, in Pi- cold and moist, so she is not in worts condition (if Ju will be in cold and dry sign it will be worst) According to J Frawley significator of illnes is here Ju in mutable sign which means illness will come and go it will be not long-lasting. So, in my opinion, she will recover.
