i believe my c7 is a cm too long (on each side), doesnt sound like much its huge compared to my t1. is it the length of the c7 in relation to t1 to determine if a c7 is big or is the actual c7 length. my c7 is 4cm.

also i read people with long c7s are more prone to fibrous bands which are prone to elevate first rib. this is not the scalenes? but what is this just a band of scar tissue? i have full neck mobility but sometimes i have "flares" where my rib goes up. wondering if this is a fibrous band, would the fibrous band have to be really bad to show up on an mri? my scalenes do not spasm. thanks!
