First up, I know there are any elbow noise questions out there, but they do not describe my experience completely.
Okay so I'm 18 yrs old and very skinny with little muscle, and I started gym a month ago.
So 2-3 weeks ago, I started getting this creaky grinding sensation when I completely extend my arm or completely bend it, you can't hear it out loud, just feel it by putting your fingers on the elbow, this sound is different from the knuckle pop or knee crack etc, its much more gentler.
I do not feel any kind of pain or secondary symptoms like swelling or locked range of motion.
When I told my trainer about it, he said its completely normal and happens because the muscle around my elbows are weak(indeed).
The sound when extending comes from a little right of the inner side of the elbow(not ulnar nerve) but when bending its kinda like from the middle of the inner elbow.
Ps.- Ever since I joined, I've been told to do wrist curls with a barbell, earlier barbell alone, then 2.5KG plates each side and currently 5kg each side. I do 100 reps of this with little rest in between.
So could it be due to this exercise? my left arm is non dominant and thus relatively weaker.
So should I stop doing these wrist exercises or just keep doing the and fortify my elbow muscles? since there is no pain or discomfort in the elbow itself while doing it.
