I am another one with the same thing going on. I have taken Mebendazole for short course and get the vibrating in my upper arms and around ribs when I take it, but maybe havne't taken it long enough. I used to get positive stool tests for ascaris, but it has been about 18 months since the stools were positive. but mainly I have these things wrapping up and down my fingers and toes, itching, making larva migrans, and taking up joint space, so lots of pain in the fingers. I also have fullness behind my eardrums. And considerable soreness in the tissues in my legs, buttocks, and forehead. I'd like to do a blood test for ascaris, but not certain where or how. My doctor is no longer helpful.
