Sit back, strap in and put on a little mood music. I suggest
Trojans by Atlas Genius, because…well, the words tell the story.

Theory: The Parasite is Arianna 1.
Failed Death Curse: In
Changes, just before Harry serves up a whole heaping helping of “see ya,” Arianna issues her death curse by mumbling a word (a focus word) that Harry doesn’t recognize. It was intended to exchange her body for Harry’s (just like Corpsetaker). So, when she died, she would possess Harry’s body, and Harry would no longer exist. But, it didn’t work. Instead, Harry remained in his body. He, also, gained another resident; Arianna. The death curse failed due to one of three reasons.
--Arianna was too weak and unfocussed to pull it off
--Harry was too stubborn, and resisted
--Lash is still in there somewhere, and resisted for Harry
It was probably a combination of all three.
She stared up at me with uncomprehending eyes, black blood staining her mouth. "Cattle. You are c-cattle."
"Moo," I said. And I lifted my right hand.
Her eyes widened further. She gasped a word I didn't know.
2.
Harry Blacks Out :Also, in
Changes, Harry blacked out for two minutes or so just as the blood curse is initiated. This makes sense, because at that moment he had an Aristocratic Red Court vampire lounging in his body. The curse attacked him because it was aimed at the entire Red Court. Something kicked in to protect him. It might have been something as simple as his entire body shutting down. But, I’m betting that Lash gave him another mental block just like she did in White Night. This, ultimately, protected Harry, Arianna and Lash from the curse, but he was down for two minutes while the curse operated.
3. Introduction to the Parasite:Our first knowledge of the parasite is at the end of
Ghost Story. Demonreach states that the parasite maintained the blood flow. Well, if you require a hematologist, a Red Court vampire should be your first choice. They know blood better than anyone. It doesn't make sense that Mab and Demonreach should have to negotiate with Lash. She has shown that she will labor to save Harry's life out of free will, and that was a big deal to her. I don't think she would hold Harry's life hostage. Arianna certainly would.
4. Headaches:Harry has been suffering from headaches. In
Cold Days, Harry develops a massive headache as he is learning about the prison well on the island. Demonreach “WARNS” it away, but not before we learn what the headache felt like. Harry describes it as two separate ice picks digging into his skull. He points out that this is what it always feels like. I would better describe it as two Red Court vampire fangs digging into his skull.
5. It Bursts Forth From Your SkullThis is a small issue, but it is reflective of a Red Court vampire. They wear a human skin, and when agitated, they shed it like…well a skin. Somehow, Arianna will eventually become whole within Harry. We know they can contract their huge size to a smaller area as has been shown various times in the series.
There you have it, guys and gals. The Parasite is Arianna. It is a result of a botched Death Curse (as she was a sorceress). I believe Lash is still in there, and may have preserved Harry's life twice in
Changes. Two's company...three's a crowd.
