Hump on 6 mo neuro squirrel??

[xcirelly]

My 6 month old squirrel (has had four seizures before, i have another thread about his seizures. cause is unknown) has developed a lump-type thing on his back between shoulder blades. It doesn't feel like a tumor or cyst. It doesn't really feel like anything. Is it just extra fur? Since I've noticed it, he's been a little clingier and antsier than usual.
He is on henry's blocks and no other medications. The only thing I can think of is that it's just a winter/adult coat coming in but due to his seizures and personality change (could also be puberty) I'm just worried which is why I have it in emergency. He is eating and drinking fine. He has had a decent amount of grapefruit the past few days.
Thanks for the help and sorry forgetting nervous and posting this in emergency if it isn't one.

Is there anything under it that you can feel? I mean, if you dig your fingers into her fur there, is there a new lump on her body that hasn't been there before? They get really thick fur in the winter.

There's not a lump I can feel. It's right between the shoulder blades.
I'm thinking maybe he's sore and it's swollen?
I don't feel anything and the fur is thick, but there isn't much of a dip between his shoulder blades.

If you can't feel a lump, then it is probably just hair. Keep an eye on it, and make sure it isn't sore to him, to have you touch it.
