The carpe tunnell effect is thyroid, underactive based. It can be RSI also so it iw worth having in throughly investigated. Its just not limited to say the writst it can be systemic, whole, parital one sided. Ankle flex issue is a known thyroid pin point sympton.
I'm full on widespread systemic now and with failing muscles, tendons, joints, bones etc.. Im physically twisitng and one side has dropped that is how bad this can go when ignored. My physio has me for life, or I se a physio for life and its for whole of me.
Physio can help but please please please ask to be treated on the whole and for an indefinate amount of time that your Physio chooses. They will assess and treat accordingly.
Also ask for a nerve conduction test. It HURTS! but worth it as is getting a spinal/neck/bone xray. Spurs can grow that crimp the nerves and cause, carpel, tennis, achilles, etc.
Warning Drs get sneaky and can say to physios treat wrist only and they will only do that. Which is perfectly fine if it is just the wrist. But if its your neck that is the real problem, working on your wrist wont do much.
Ultrasound of your neck on the cartoid and aorta veins and arteries is worth asking for, sound test on it too. It can hi-light any issues.
My cartoids and vertebal arteries are restricted due to the spurs on the vertebra pinching them and also my swollen bumpy thyroid and all enlarged reactive lymph glands are pushing on it too.
