Lumps found on my adult male fox squirrel, please help

[Squirrelsaremyhomies]

Hi, my Simon just turned one year old (today &#128156 and I have found two lumps on him. He is indoor/outdoor, meaning he chooses when he wants to live in the woods or in my house. Currently he's been inside for the last week (since 1/31). On Thursday 2/3 I found a lump on his back; it appeared out of nowhere. It is under the skin and large. It is relatively soft and does not bother him when I palpate. On Saturday 2/5 I found another lump on his lower abdomen. The second one is smaller (size of a pea), and harder. He sometimes grooms it, but it does not cause him pain when I palpate. His energy, mood, pee and poop are all normal. I am so worried and don't know what to do. Please advise; he is my best friend 💜🙏🏽

Curious to see the one on stomach, the one on his back resembles a bot fly larvae.

I can't figure out how to get a photo of the lump on his abdomen. It's not visible; I can only feel it under his fur and skin. But it's not the same size or consistency. It's much harder, and smaller than the lump on his back.

How long does it take for a bot fly larvae to form a lump? I'm asking because Simon had been living outside consistently, until last Monday 1/31 when he came back in. The lump did not appear until Thursday 2/3. What's the turnaround time to see a visible larvae lump?

Also - it does not bother him when I manipulate the lump on his back. Is this normal for a bot fly larvae?

Thank you so much.
