Aches & pains--anyone else?

(Warning: pregnancy mentioned and its aftermath discussed)

My weird body is at it again.  I think I'm the only twin mom I know who didn't have lots of back pain during her pregnancy.  Sometimes I had pain in my hips (which I attributed to lying on my left side so much), and I had bad pain in my wrists and hands which my OB's NP told me was probably carpal tunnel syndrome. . . . but both of those went away within a few weeks after delivery.

(Oh, and don't have get me started on my c-section-related complaints!  Over five months out, I still have an area between my belly button and my incision which is numb; after healing beautifully for the first few months, a portion of my scar recently has started forming a keloid and often itches; and I sometimes get random shooting pains to the left of my numb area and/or itching that cannot be relieved by scratching or odd cramping feelings around my incision site.  Sigh.)

Back to my back pain. . . . I felt an occasional twinge, likely due to muscle fatigue, when I was home on leave with the boys right after they were born.  But I figured that was normal because I was doing so much lifting and carrying of babies.

The real back pain has started since I went back to work at the end of March.  During the first full week I was sitting at my desk all day, I managed to "throw out" my back just by sitting in a position too long.  It was crazy: one moment I was comfortably seated, looking at my computer monitor; the next, I tried to stand and got halfway up before being seized by a terribly painful muscle spasm which prevented me from straightening up.  The pain and tightness persisted for almost a week after, although after the first two days, I could at least straighten up enough to walk properly.

Before I ever got pregnant, I had suffered with symptoms consist with piriformis syndrome in my right hip, and though I was never officially diagnosed with this, I had treated it with massage and stretching, with pretty good results.  Despite not being able to stretch or exercise, I never had any problem with this while pregnant, but since returning to work, I've noticed a lot of pain and tightness in that area and also occasional numbness/tingling in my right thigh again.

I have tried yoga (not as regularly as I should, but I have done it 1-2 times a week on average), stretching a few times a day, getting deep tissue massage, taking ibu.profen.  All of these things have given me some limited relief, but the pain and tightness persist and are worse some times than others.

In addition to this lower back pain which appears to be interconnected with my hip tightness, I also sometimes have pain in the middle of my back (between my shoulder blades).  That seems to get worse after lying down for a while, so that if I have to wake up in the middle of the night to tend to one of the boys, I sometimes experience a shooting pain there when I try to sit up.  Not sure if it's lifting the boys, bad posture, too much time at the computer at work, or some combination of these that is causing this pain.

I know my core has been weakened by my pregnancy and by a year of very little to no exercise.  In addition, I'm sure my abdominal muscles are stretched out because my lower abdomen in particular looks "poochier" than it ever looked before I was pregnant, even when I weighed more than I do currently.  And when I lie on my back and put any pressure on my lower abdomen--either pressing with my hands or sitting one of the babies on there, for example--it actually causes some discomfort.

I've considered going to my doctor about this, but he is likely to recommend physical therapy, which I simply do not have the time to do.  I am perpetually behind at work these days as it is, not to mention my personal commitments.

If you've gotten this far, thanks for reading.  I guess I just wanted to put this out there and see if I'm the only one who's noticed these changes-for-the-worse post-pregnancy, and if not, what others did about them, if anything.
