Are these herx symptoms?

I have started a new treatment (UVLRx, which is IV ultraviolet light therapy for those not familiar). I have been having some obvious herx symptoms (pain) and some other odd symptoms. Please tell me if these sound like die-off.... I have this strange stomach pain (vary random and intermittent and lasts only a second or two). It feels like a sore muscle, but is quick and sharp, stabbing, then goes away). It is to the left of my belly button and just above (I THINK that's where the stomach is...)

The other is horrible itching almost exclusively at night...mostly hands and feet, but also belly.

I WANT it to be herxing...! I was concerned that something else is wrong with my stomach...it seems so odd to me...almost feels like how it felt when I was pregnant and I could feel the baby move.....so strange!

Yeah...need to do more detox...

also, I am extremely bloated, despite near perfect diet.....

My first thought was parasites. They become more active at night. And also you said you can feel something move...
