There is always hope and I've killed many parasites... I've had the prickles and stinging behind the shoulder blade which is probably larval migrans.. not sure if its the same thing as you're experiencing.
Sometimes the paras come back so we need to keep on top of them. Sometimes the situation does get scrarey.. just know you aren't alone. We're all in this together. Hope you get some sleep and tomorrow will be a better day, goodnight x
