I read your post and it is old so maybe you won't even be on this forum to follow up but I hope this gets to you.
I am curing my asthma, histamine overactivity, fibromyalgia, CFS, IBS, Chronic pain, IC, allergies and a disease like MS is in remission by several different things. I practice Alternate nostril breathing (Youtube to learn how) as breathing out of one nostril more than the other or unequally can cause/worsen asthma. I have taken for years H1 and H2 drugs for the histamine response in my body plus GERD meds only to find out I had a walled off nest over my bile duct with flukes and stones and many different kinds of worms an those meds were keeping them alive. I had a coloniscopy and nothing was seen and years of negative stool o&P. I prophactally took parasite cleanses twice and year with no results.
I juice fasted for two weeks and became constipated because it broke them loose and got stuck in me. I went for a colonic and there came a deluge for the next 7 weeks which I am still trying to kill but the good part is that my GERD is almost healed, my allergies are mostly gone, no more histamine episodes, my skin hives/rashes are gone, my CIDP (like MS disease) has gone into remission, my bladder that the doctors wanted to instill a pacemaker into is working the best it has in 15 years all because I am getting rid of parasites/worms. So I personally had them and was worse. I would never have an instillation to try to cure myself as I found over the last year just changing my dosha Ayurvedically has begun curing me. I take the ayurvedic herbs for worms and constantly pass chum. My illness's cause me great Depression and anxiety due to loss of quality of life but now that these worms are dying off, my Depression has disappeared, I'm no longer apathic and hopeless and the anxiety is lower the less I have in me cause they were stirring up anxiety in my body and I didn't know why cause I have a pretty good life except for my disabling illness's that now seem to be getting better. I've spent more than 750K over the last 25 years trying to get well and what if it has been parasites all along and only cost less than a couple grand to eradicate them? I'd never get these put in me. When they start jumping around I almost become suicidal. For years, my psy has thought it was delusional parasites cause I'd say they were biting and moving all over my body and now with pictures and witness he could be sued for malpractice. Now I barely feel them anymore but I still have a long way to go but at least now I have the emotional capacity to see it through. I have found the best healing through acupuncture, breath work, ayurveda, biofeedback, massage, reiki, cranial sacral therapy. I rarely need a MD anymore cause I don't respond to their treatments but I am taking the meds to rid myself of worms. I just can't wait out the herbs the whole time. Ayurveda panchakarma balances my doshas and has practically cured my chronic stuff. Good luck in your search as it took me half my life to find things that worked.
