It might be even worse than Ascaris, it might be Tapeworm larvaes! I have the same symptoms as yours - tiny black hairs and larger white/transparent threads.
My 4-year battle experienced me with different drugs, listen and remember - some worms seem to die off though they wait till the end of the cycle and attack again. In consequence you harm your liver because of poison coming from drugs, lose immunity and worms become stronger. Do not use drugs longer than for 2 weeks in one cycle.
I started with Albendazole and thought it was the one to help me, refusing the fact worms might have been Tapeworms or flukes. Now I'm absolutely sure they are something worse than Ascaris or pinworms. I've been trying Praziquantel lately, works better than Albenza.
