solar plexus, or Celiac plexus

RG,
Do you know much about the solar Plexus? I have a lump and pressure in my diapham for about three years that also has discomfort and pain, I always feel like I have to stretch my back up to breath. I am on my 5th day of Humaworm and I had this big movement in this area about 30 minutes after I took my evening dose.
Any info would be good.
Thanks,
Shelly
