Hi and welcome.
If I am understanding your situation correctly...you have some chronic pain issues that you have somewhat exaggerated to call attention to your condition..and now you are feeling like you genuinely have another, more serious issue?
What is the cause of your original pain? Could it be this health problem has simply gotten worse? Are you managing it well? Under the care of your doctor?
I guess that I would just suggest consulting your doctor to rule out anything else going on...and if you feel like the hypochondria is getting out of hand, then seeking a therapy consult.
I hope that you get the answers that you seek soon, and post anytime with questions and concerns.
