I realise you are not all doctors but in 2017 posters on AIBU helped me find out what pregnancy complication I was having when docs couldn’t so....
Anyone got a clue about this. Left knee, one day felt burning pain on skin, almost like a cigarette was being put out on it, but no mark or injury.
With increasing frequency now, intense burning pain that must be coming from inside but feels like hot burning skin. Took a week off exercise and no improvement.
Does it sound like anything you know?
