There are some good natural treatments. They've been developed, trialled, refined and approved as medicines. They're available following a consultation with a GP or similar, and a local one can be consulted if you're away from home.
Given what's been said about how serious this might be, stop looking for the best flavour of homeopathic water and go find a medical professional.
Apologies if this is a little too terse for you but if you're concerned enough about it to post on here, then you should be concerned enough about it to seek qualified advice.
