After the vet said my 13 yr. old dog had hip dysplasia since she was atrophied in her back legs and couldn't hardly get up for about 8 yrs. I started to deworm her regularly about once a month, she is completely well now. Seeing how detrimental it is for livestock. And researching human worms on the internet. And watching worm videos on Youtube. Vegetables from organic manure composted gardens can transmit worms. Eggs float like dust and can be ingested. Especially wormey dogs in the house make eggs in dust. Most everyone has worms. Worms make same symptoms as fibromyalgia. Only 20 percent of doctor ordered fecals show worms when they are really there. Pin-x or Reese's pinworm medicine is over the counter, non prescription at the pharmacy. There are a couple other brands also.
