My ICD aches most of the time it feels like a knife in there cutting me, I can't get any definite answers

My crt-d does ache every so often ..it's scary..I feel something is going to happen... the ache comes and goes...the Doctor and Tech that checks my crt-d says it's normal...but it's still worries me.. God bless 🙏🏻

8I guess I am lucky with mine. I have had it 3 years. I am never aware of it. I feel nothing.

Every once in a while it aches i assume for the most part its what i do on that particular side

Yes mind does at times very irritating and frustrating but have got somewhat use to it
