I am so glad you went, and perhaps we should have said what to expect!! I am sure she will have seen worse or maybe not
. Quite possibly next time it will just be leggings down a little, at first appointment or if anything major happens, they need to see how you stand, weight distribution etc., It sounds like she was really good.
I usually just lie down now, my physio presses on my back, to try and open the spaces in between the vertebrae and then I get a lovely large, warm Tens pad put on and she leaves me with a few acupuncture needles in, you can't feel the needles, so don't fear them if she suggests it.
L3, is one of the vertebrae in your spine, they are numbered from the bottom up, L stands for Lumber. I had a disc herniation at L4/5, which means the squishy stuff between the vertebrae had pushed out the normal space which can then press on the sciatic nerve, this is a nerve that runs down the back and then down the legs into the feet. If the nerve is pushed too hard, then the pain down the leg can be excruciating (Sciatica), but it comes at various levels, sometimes the disc only protrudes a fraction, or just gets bruised and causes only back pain, sometimes the nerve is touched a little and you get burning in your bum cheeks. I am sure it is linked with your SPD and also pushing during delivery. If you are on your back it puts a lot of strain on the spine, then you go home and lift a progressively heavy weight for years!
Do the exercises religiously, but only as far as you can, don't think the more you do, the more you will heal it, it doesn't work like that, if it is painful, stop. However, you do need to keep moving, ideally walking.
I hope she was positive about it, don't read too much on the internet, I managed mine for 30 years (God that makes me old), with only a few glitches. Do it right now and you will strengthen your back and won't have any!
I had a cleaner come today, she did a 3 hour clean, it was weird having someone clean your house and some of it wasn't done as I would have liked, but I wasn't brave enough to say so! I need to get one weekly, as even though she didn't stop, you can't tell and I know my othe rhalf is gong to come in later and ask what's the difference!? Men don't notice, skirting boards, toilet bowls and kitchen cupboards!
