I think the best thing is to figure out which bugs you have asap.
You should really try to get a diagnose from a lab if you haven't. parasite symptoms are very similar to other things and knowing which bug you have will help you with the right dosage and medication.
parasite labs are very unreliable and often give a false negative test result. You may have to test several times and at different labs until you get the proper diagnose.
Good luck and keep in touch.
