Welcome to the boards. You will hopefully be getting a full written report through from Dr KK in a few weeks, which contains more info (that you can google or search on here for
The thoracic spine is a region of the spine (When looking at or talking about the spine, medics split the spine into discreet portions - the cervical (at the top), the thoracic region (mid-spine), lumbar (lower-back), sacral or sacrum (where the spine meets the pelvis) and the coccyc (the evil bits at the bottom). The thoracic region is the longest portion. You can google spinal anatomy if you're interested. Having hypermobility in that region means your movement is more than a normal persons would be in that region.
For the feet bit - this is classic HMS or EDS feet. We have nice high arches but when we weight-bare our feet flatten out and the arches disappear, most often pronating. This means the foot rolls to the inside edge on weight-baring. You may need to see an orthotist or podiatrist about getting insoles to correct this. Have a search on here we have lots of posts about feet and insoles.
HMS or EDS people tend to bruise easily and we also tend to heal more slowly and also can have poor scar tissue - in particularly paper-thin scarring (papyraceous scarring). Your BCG scar may have been your only or most obvious example.
We also tend to have digestive and gut problems, IBS being one and dysmotility another. This is just a fancy word that means stuff doesn't get moved along the digestive tract as well as it should and also we have a harder time pushing stuff out (sorry for tmi
). The theory is that our guts are just as stretchy as our joints and skin, so have difficulty coping. Movecol is basically a kind of goop that you drink that helps lubricate your insides and bulk up everything so it all comes out easier.
Lots of us have low vit D (also low calcium, which tends to go hand in hand with vit D, so get that checked by your GP). You do get it from sun but also from your diet and if you're having gut issues then you may not be absorbing enough from your dietary intake.
