Update with new diagnose "costochondritis"

[newhere]

So,before few days i had a visit to my local neurosurgeon.
I copmlained about upper back pain and pain in chest...
After his examination,he decides to give me injection...he try to to provoke my pain,and was successful after presing my 2 rib where conecting my sternum.it was so big pain...esspecially on the left side,on the right not so much. He say i have costochondritis and decides to give me injection of lidocaine...and IF this helps later he will try with costisteroids. i feel great 1 week(no more pain in chest and no cracking at all)...feeling was great,altough this didnt ease my pain in upper back AT ALL. Now after 1 week i have pain again,so im waiting for 30.08 for steroid injection.
For upper back,he didnt say something special,he gives me new pils,antidepressants & some baclofenum who supposed to relieve muscle spasms.
I am so courious,if this can be somehow related with upper back problems?
I read if the tissue in front ribs are bad,this can happen behind in spine also.
This behind is called costovertebral something,what esspecially marks knows since he goes for this type of procedure.
If someone have similar problem or some info,i will appreciate it
tnx and sorry for my bad english grammar :/
