[|Human|] My girlfriend and i were laying in bed and she niticed a very sharp pain, needle-like, that poked her in the back of her left calf. and there was a moving, purple line about a centimeter in length. she says she can feel it moving. she is freaking out and ready to puke. that seems to be the only symptom. i dont know what it could be. i hope to god it isnt a parasite.
[|AI|]  Hi, It would be best for her to see a doctor for an assessment since she noted an area that appeared to be moving. A parasite would need to be ruled out. If one is present it would easily be treated with medications. Medications are usually highly effective in treating these infections. Her doctor may also recommend blood tests and possibly imaging as well to take a look at the leg. I hope this helps. Let me know if I can assist you further.
