Your orthopaedic consultant is shit then!
Because everything you mention that’s physical points to Eds (ehler Danlos syndrome)
Which my dd also has. But took us until she was nearly 12 to get a referral to orthopaedics.
But our consultant spotted it straight away. The tests merely confirmed.
Eds causes ALL the muscular tissue in the body to be too stretchy too soft.
The heart is a muscle and “over” stretches when filled with blood in people with Eds causing palpitations
Nerve response is heightened - they hurt more
The body overall has to work harder to control ALL movements even breathing so they get more tired (try to think of it as they’re doing low level exercise CONSTANTLY)
Chronic pain throughout the body but especially joints.
Continence issues - their muscles there just don’t work as well as others, when they gotta go they HAVE to go!
Gets ill all the time - they are particularly prone to mucous membrane infections. Catching them in the first place and get them MUCH worse than others. My dd was hospitalised a few years ago because of a very common infection most people don’t even visit their dr for. In her because she has Eds it resulted in her losing a LOT of weight fast (and she’s already painfully slim because of it! They have a higher metabolism too, plus they’re using more energy with the work their body is doing to maintain muscular control) becoming dehydrated and acquiring a separate bacterial infection on top. She was in over a week on drips and wasn’t allowed back to school straight away once home (and she wouldn’t have been up to it, she could barely eat and walk to loo). Don't want to say exactly what here but happy to pm.
They have soft “velvety” skin that injures VERY easily and is very sensitive. The skin splits and bruises at the slightest touch. At one point I worried about leukaemia because she had a load of bruises with no explanation how she got them.
Please do look at Eds info elsewhere but that’s what your post shouted to me.
