I also think I tend to ignore my body and symptoms frequently. I have been told by doctors time and time again, "you have a high pain tolerance" and that I should have come in earlier for treatment.
My perception is that I have a much lower pain threshold than most, and pain tends to be a trigger for me and I get really distressed by it. That said, I do tend to just ignore low-grade pain or other symptoms.
I get colds and flus at about the same rate as my work colleagues, but I tend to have a lot more time off work than everyone else (except for another colleague who's also dealing with past trauma). About a year ago, I was diagnosed with a low-grade chronic inflammatory disease. I'd always assumed it was just IBS, but turns out it's not.
I have a tendency to somatise a lot of the emotional pain. I kept it buried in my twenties that way and I lost most of my twenties to not facing up to the trauma. I still have occasional tendencies with that, which is one of the reasons why I tend to ignore illness as much as possible. My doctor and I often have trouble working out what's real illness we need to deal with and what's emotional stuff I need to work on. Dizziness, headaches, fatigue and generalised pain are typical somatisation symptoms for me - but they overlap with so many physical illnesses (eg colds and flus) that it gets confusing at times.
