Hello - This is not very unusual when parasite cleansing. It is from the toxins. Flushing out your sinuses will help. Take a suctioning bulb - made for infants - and fill it with warm salt water - salt the water until it is like tears. Hold your head over the sink and flush the water through one nostril until it runs out of the other nostril. Repeat on the other side. This might give you some relief.
