Sliped disk?I have horrendous back and chest pain , I'm worried

[Chocolate2020]

About 6 years ago my gp said I have costochondritis , the tight upper back started in 2006.

It started to become a tight chest that would crack if I put my shoulders back now
I'm now in my 30s the tightness is there 24/7 and it cracks constantly, my back always feels tight and if I push on my chest it hurts .

What's really worrying me I've now developed an awful pain that hurts when I sneeze or cough , take a deep breath , it's on my back and feels like it radiates through to my chest to the other side , It's like the stich you get from running a sharp pain .
I've included a pic of where abouts the new pain is
I'm worried 😟

Hello I have the exact same pain was awful due to heavy lifting shopping and at the time I was only in my 20s anytime I would breath it’ll hurt, pain gave me so much anxiety couldn’t do anything. Done so many scans, mri but couldn’t see anything and was later diagnosed with costocondritis. As time went past it would get intense and unbearable but what really helped a lot was painkillers and resting. Pain goes and comes for me but not as bad as how it was. Get some rest and try not to stress, stress played a big part and would trigger my flare ups❤️

My pain was located on my chest wall, shoulder/ shoulder blade, my upper back, neck and also felt so stiff

I’d call the GP in the morning and insist on being examined. If the pain has just come on suddenly this evening and you’re really worried, call 111 but as you have chest pain they are likely to send you to A&E. I’d go with your gut instinct - if you feel really worried, I’d probably not wait until tomorrow.
