I googled your symptoms and they are an exact match for Flouroquinolone toxicity. I did not look up flouroquinolone to see if it is a fluoride based drug because it seems rather obvious that it is. Presuming that is correct, your cure is Iodine, because that will get the fluoride out of your system. And the bacteria that caused you to need flouroquinolone, and the bromine and the heavy metal.
What kind of parasite was found? Maybe the parasites are not related to these symptoms. None the less, you want to get rid of them to avoid complications. So take Clarkia and do the entire cure zone cleansing protocol. It will cure just about anything that ails you. Then maybe a ten day Water Fast to seal the heal.
