I have experienced the rope worm in the back of my throat, but not to the degree which you have described. I'm sorry to hear you are dealing with such a severe case.
There is hope!
What I have had great success with is ozone. If you can find a practitioner who offers ozone you can breath ozone and have it put in your ears. You can also have them let you inhale the ozone up your nose in a concentrated amount and then you just hold your nose and breath for 1 to 2 minutes and then exhale out. I believe the latter is the most powerful in dealing with the rope worm in the throat.
If you can afford it Ozone therapy is potent and effective!
