I think you should also reconsider how you write/talk about the issue. On the same tone as the talking to the infection comment, you're a multi faceted being and so when something is this chronic often the different levels are intertwined and re-enforcing eachother. This is potentially why you can see failure trying one remedy at a time even though it worked a treat for someone else. So on the physical level you want to be aiding your body fight off the virus, ginger, nano silver, gold, etc etc. Energetically yes sound/music is one way to re set the vibration, but also, and very important not to miss, is the psychological subconscious programming that is formed around this. 'I've had it for 3.5 years, it wont go away, no matter what i do'. Its almost like you need to view your subconscious as an eves dropping child. We're all aware these days of the effect that negative parenting behaviours have on children as these actions programme their software/subconscious which which you/the program needs to run through. Your subconscious is just the same, you can't directly hear it, but it can hear you. You are programming it to not go away no matter what you do, that is what you believe and the subconscious as a child wants to please you and so gives you what you want. It's a lot to get your head around, i haven't fully and am striving to learn more through research and meditation. But i think it's something you're going to need to address to tackle this as it's chronic and not acute, meaning it's programmed, but it can totally be undone. Bruce Lipton has hours of videos and books on this.

But yeah a good way to start out is write out all your thoughts about how you feel about it. eg- it wont go away no matter what i do. Write next to it an alternative sentence. It has not gone away yet because I have not got all the information and understanding i need to help my body rebalance. I will find out this information and It will be healed.

Or another thought might be one of frustration- I just cant take this anymore, why wont it go away i've tried all the best remedies i can find. Change it to, It is causing frustration but i understand now it is serving a purpose, to teach me there is a gap in my understanding, that i am not balanced in something. It's actually trying to help me, so lets work it out etc etc.

Good Luck!!!
