I've been going to the gym regularly last few months doing a 4 day split.

Last few weeks I've had this "sensation" on my right shoulder. It wasn't pain exactly, more like slight discomfort of which I didn't give much thought to.

I did a back workout 2 days ago (with lots of overhead pulling movements) and was feeling fine yesterday. Last night has trouble sleeping and woke up this morning with this soreness around my front delt on my right shoulder. If I raise my right hand up and then pull it down, I can feel the soreness increasing when my hand is going down especially when my elbow is level with my shoulder and going down.

Is that Shoulder Impingement? If so, appreciate any advice from anyone who's had the same problem. I rather not go to see a private doctor yet as I don't really trust them to give impartial advice.
