Normal muscle is pliable in most cases, so I don't know how the jelly-ish feel would compare to the normal or ??

yes, muscles that are hard /firm or bumpy/lumpy is usually spasms & or trigger points if specific small sore spots

my forearm muscles were described as ropey by PT during the worst times.

Now they seem to have lentil sized bumps along the tendons or muscles - but they don't hurt or seem to be an issue so haven't had them checked out.
