@Dontgiveup I have ALL the symptoms you described in your original post, including severe leg, hip, back pain and stiffness which comes and goes and severe breathlessness and tachycardia and temperature changes. This is a picture of my collaterals.
Also at the front which I’ve tried to look into and it doesn’t seem normal to me. Does anyone else have this?
There also seems to be quite a lot of gubbins around the vertebral artery on the left hand side which I have wondered about as so many symptoms resemble vertebral artery insufficiency.
