YES, in fact, it's possible. There are different types of flukes, which could make such pain, I know it from myself.
After two liverflushes it became better, but I've learned doing a parasite
cleanse before is VERY important. And I believe, the 21-days-regime from Hulda Clark
I've passed 2 liverflukes after my second liverflush. The pain is already there, but much less then before.
You will feel the time when doing another flush or another parasite
cleanse is necessary. The pain and some other symptoms worsens if there are again parasites
to kill. In my opinion, it's a longer way, but it seems to be possible to get better.
Start your way and good luck!
