You could try giving her some vitamin D3 supplement from the pet store (must be D3 they can't absorb other d vitamins) at 3x the recommended dose and see if she starts to improve after a few days, if she does continue for 2 weeks.
If her particularly brutal molt has upset her absorption of the balance of nescesary vitamins and minerals they need it could have caused a form of rickets. No other ideas I'm afraid.
