4 lumps in my arms ultrasound

[switchoff1]

Health anxiety is coming into full swing today. Just had a GP appointment (yes on a Saturday afternoon I was surprised!) I’ve had a couple of lumps in my left arm for a good while probably over covid. Recently found 2 in my right arm. GP is going to refer me for ultrasounds on them to determine if they are fatty lumps or cysts. Where does it go from there? Apart from determining what they are. Obviously been googling a lot lately and worked myself up. She also mentioned checking for diabetes. She seemed more concerned over the number of them as she said it was a bit unusual for multiple so that’s freaked me out. Anyone else had a similar experience
