hi G,
no you're not whining. and yes it's time to call your pcp.
i've been dealing with back pain and finally had an mri 2 yrs ago. i needed some injections and that did the trick for 2 yrs. i needed a series of 3. but it worked. reduced the disc swelling etc.
now the problem is "back"

and i had more injections before my surgery.
my dr thinks some of my left leg pain is still from the disc so i'm looking at more. but, they really do help. better than surgery.
i also have deep tissue massage, wkly. my massage therapist can tell if it's muscles or not. but only the mri told the real story. i even had a small tear in one of the discs.
long story long, please check this out with your dr and decide what to do.
the fact that it's cont'ing and getting worse means it's time to get things checked out.
