Lately (last two weeks or so) after doing chest work or shoulder work, both my shoulders will get very tender at the anterior deltoid (if my anatomy is correct). Wished I had a chart so I could circle the exact spot. Equally tender on both sides so my first thought is it's not an injury type pain but it sure gets sore to the touch. I don't remember ever getting this sore this fast (within an hour or so and gets progressively worse for about 12-24 hours before getting better. Is this just normal soreness that goes with lifting (I am over 50) or is something worse going on?

Today was moderate weight/high reps for chest to include flat bench press (185 x 15 for 3 sets), flat bench flyes (40 x 15 for 3 sets), db incline (30 degrees) (50 x 15 for 3 sets). Also did dips (bodyweight), reverse flys (25 x 15/3 sets), skullcrushers (80 x 15 for 3 sets and db lateral raises (20 x 15/3sets). Nothing extreme but still got the soreness.

I tried dmso cream with limited relief...
