"Serrapeptase digests non-living tissue - blood clots, cysts, arterial plaques and inflammation in all forms.
Serrapeptase is in wide clinical use throughout Europe and Asia and is a viable alternative to Salicylates, Ibuprofen and the more potent NSAIDs. Unlike these drugs, Serrapeptase is a naturally occurring, physiologic agent with no inhibitory effects on prostaglandins and devoid of gastro-intestinal side effects."
It sounds like the "herbal" cleanse you are taking is only making your condition worse by aggravating the parasites into a desperate attempt to spore more eggs by creating more cysts.
If it were a cyst on the skin, you could have the doctor inject you with hydrocortisone to get rid of it, but since it is inside your wrist, you don't want it to break, as doing so will circulate all the parasite eggs in the cyst to travel throughout your body.
If I were you, I would try the serrapeptase and stop the herbal cleanse. Also have you tried coenzyme q10? A super high dose supposedly kills off parasites. 3000mg.
