Hello~I have been doing some searches on-line, it looks like everything is very expensive. I am attaching a link to one site, yes, the products are expensive, but it should give you some idea as to what may help. Also, maybe ask the pharmacist or a trust-worthy Naturopath, they sometimes can come up with ideas that a regular doctor has not thought of.
I hope you find the help you need.
