Mange mites are a microscopic parasite that burrows under the skin, causing severe pain and itching. In the later stages, it causes hair loss, and deep scabs from the animal scratching themselves so severely.
Veterinarians test for mange mites by doing a skin scraping. These are inconclusive, and come back negative over 50% of the time. This is because the mites burrow deep into the skin, where a scraping cannot reach them.
My guinea pig with the most severe case of mange mites was taken to the vet. He did 3 painful skin scrapings, and all came back negative. In the end, she had lost all her hair, was covered in scabs, and having seizures. He still did not believe mange mites, so I treated her myself. Within a month, she looked like a totally different piggy.
Mange mites CAN be treated at home yourself, but must be done with extreme caution. Ivermectin, or Ivomec, both which are sold over the counter, are what is used to treat mange mites. It is done in 3 doses, 1 dose every 7 days.
Here are some very important links that explain all about mange mites, and treating them yourself:

However, I must stress this, if the guinea pig is having seizures, and is unable to stand, he REALLY needs to be seen by a veterinarian as soon as possible. Mange mites does NOT causes paralysis. It can cause dehydration if the animal is in pain and refuses to drink or eat. It can also causes lethargy for this reason. However, mange mites are just one possibility, and before even thinking about treating him, he really needs to be seen by a veterinarian. Something neurological can be going on, that only a veterinarian can determine.
Hope this helps!
