hi mark g : have you tried using a suana in the past ? , it makes sense to me that if toxins are trying to exit the skin , but you are not sweating then you could be holding up progress and this is where the itching would come in , if you can't find a sauna ,then the next best thing would be a hot bath and soak for at least 30 mins , this will open the pores and release some of the toxins
