I have the same type of muscle spasms/twitches all over my body (which followed initial and ongoing intestinal pain and spasms).
I tried a couple rounds of Praziquantel and Albendazole which settled everything in my gut down while taking it, but it did not last afterwards.
I tried one 4 day round of Ivermectin and Albendazole (with Doxycycline).
This did not seem to make any difference in intestinal or muscle symptoms at all.
And I started getting pain stomach (I think from pet Doxycycline)
I was wondering about your Moxidectin use -
Did it cure you after one dose?
How much did you take (its in a paste, right?)
