you wouldn't be able to see unless you actually try some parasite cleanse for actually 2 months (it was my case)
but you know, we can not just wait on doctor to save us from our illness. we need to move deligently and try many possible things and finally we can find right track. I think it is worth to try. the bible says ask, and it shall be given to you, seek and you shall find; knock, and it shall be opened unto you" May God have mercy on whom seek and knock.
