Need help! Physical.

I need some help. I was diagnosed with schizophrenia two years ago.

I am wondering whether any of you feel this physical sensations in the body where it seems like something in the body is on fire. It feels like I am always anxious because of it. And it seems I become catatonic when I focus on it. I’ve also got a bit of epilepsy when I focus intensily on it.

Is this normal? Or am I just too sensitive?

Did I break something inside my body? Is it brain damage? The region I’m talking about is the spinal cord.

It makes me lose touch with reality sometimes. For ex. when I become too sensitive and this sensitivity starts to get quicker I hallucinate.

Any help would be appreciated.
