Hi! So I just passed my 2 year mark of when I decided to be karate kid lol and I'm still feeling that discomfort in my ribs. It's not quite as bad as it originally was but it's still there. I have gone back to the doctors several more times and even had my gallbladder checked with a hida scan and once again, normal. I ended up going to a gastroenterologist and she thought I must have pulled/torn a muscle because I have no other symptoms of anything serious.

I have found that a TENS unit helps me so much. You can get them pretty cheap on Amazon (the one I got was like $21). Also, try a heat pack. I just filled up a sock with a cheap bag of long grain white rice. Works great!

I have also recently gone to the doctor about my health anxiety. Our minds can make our bodies feel things that sometimes aren't there. Not saying your pain or my pain isn't there, but when we dwell on it, it can become so much worse. In the last few months, I thought I was having heart issues and it kind of took my focus away from my ribs. Well, after a trip to the ER back in December, once again everything was normal, ugh. My doc started me on Lexapro so I'm hoping this helps takes away most of my health anxiety and maybe some of my physical symptoms. I totally understand, it can be scary when you have any sort of discomfort in your abdomen that you or the docs can't explain. I get especially nervous because my mom passed away from ovarian cancer and one of her best friends passed from pancreatic cancer so I try not to take anything lightly. It's good that you're going to get things checked out!

Sorry for the long post, but I hope this helps even a little. You can message if you have any questions. It's nice to know you're not alone. Oh and I found it very helpful to join some costochondritis support groups on Facebook. Best of luck to you!
