Ok, so this seems a bit odd.
I currently have a buzzing sensation (like I’ve sat on a phone!) in my left buttock/lower back. I had the same thing in my lower leg a couple of weeks ago-I thought I was leaning on something!
I’ve googled it, as you do, and it says it can be caused by Arrhythmias. I had an episode of AF in November and am currently waiting for an appointment with cardiology.
Has anyone else experienced this strange sensation. I feel perfectly fine but it’s a little irritating!
