I am not sure what to do and Google has only confused me.

I have an SD card that appears fine physically. However when I place it in 3 different computers it doesn't read. My camera won't recognize it either.

I have tried a recovery software to no avail. Though that did fix another of my SD cards. I am missing 1000s of pics on these 2 SD cards and am unsure of the next steps. Any assistance in guiding me to a fix(or even a professional recovery service) would be much appreciated.
