Strongyloide roundworms can leave cut marks just like you described. Strongyloides hatch in the lungs and when they are small larva they can move into the sinuses and they also move just under the skin causing the marks.
Humaworm will help remove them and the RG's Medicated Cream is excellent to use on the skin.
Do your Humaworm, wait 90 days, then do it again. There are some other things you can do during the 90 day waiting period (lung, liver and kidney cleanses) BUT you must wait the 90 days before parasite cleansing again. You do not want to create resistant parasites by cleansing too often.
I am so glad you got to the root of your problem! Things will get better now for sure!
