What are some somatic obsessions/compulsions that y’all have dealt with?

Anyone else struggle with somatic OCD and any pain/feeling slightly different is so noticeable and you feel like you’re just going to collapse or something? Like my ocd always convinces me that any sort of pain is related to some kind of illness that can cause a bad outcome or even death. If so, please share your tips of how to improve with this type of ocd 😭

I haven't been able to read about experiences similar to mine when it comes to my perfectionism OCD so I was wondering if anyone had any "uncommon" experiences.

If you can elaborate on them, I would be more than happy.
