Noval Shoulder pain

Hi my name is boris im 24 years old.
im benching 3 times a week currently and progressing linearly.
Yesterday i felt something strange after the workout like very little discomfort in my left shoulder.
today when i woke up i feel 6/10 pain when abducting and adducting the shoulder. The pain is mainly in the acormion even without movenent i feel some itching in that area(acormion)
i feel pain when driving and getting the shirt off etc…
Also i feel very small bump near that area (ac joint?) its invisible but if i touch it i can feel it a little swollen.
i didnt feel it durring the bench itself only after.

What should i do?
Can i keep benching ?
Or give it a week or so ?

Hey Boris,

Sorry to hear about the shoulder issue.

Have you suffered any recent acute traumas to the area?
What has your training looked like recently?
Has this happened previously?

Hi doctor,

No i didnt my shoulders was always healthy.
im after 6 month layoff been traning 4 times a week basic linear progression 3 times a week bench,3-6 reps of 90kg.
first time, if i touch the acormion bump it hurts 5-6/10.
Rotation no pain, bench(light, didnt try heavy yet) no pain and push up no pain.
but reaching to my second shoulder i feel 6/10 pain.
as i said driving a car hurts when i use this hand.
