Arm pain during and after Squats

[Ronin]

Hi, first post after lurking on this site for some time. I'll try to give background to help clarify but also try and keep it as short as possible.

After doing high bar squats hitting 295 on linear progression SS program, I decided to try and properly do the program with low bar. About 2 weeks ago I did a large deload down to 185, and continued to 225, 255, 275, 295, and back on to LP for most recent 300 lbs. This was in effort to learn where the bar sits in the groove of the back; Except as I got closer to the 5rm, I started to feel an intense pain where I can only describe as where the shoulder deltoid and outer tricep meet ( right above my forearms). it started with my right and has migrated to both arms. It hurts enough that I can't finish intense squats or the rest of my workout. No pushing or pulling.

I am located in Germany so there is no coaching available. Because of this I am doing something I otherwise would never do, and that's sharing my shirtless back to help alleviate my problem.

One thing I'm aware of is, I have very limited mobility of my shoulders to create a shelf by bunching my back with a close grip. I saw someone else have this problem and the only way to keep wrist in line with forearm is to really widen the grip and allow thumbs extend over the bar. I have a feeling this extra wide grip is whats creating downward pressure on my arms???

If this has been covered before, many apologies.Please just direct me in the right direction.

Hopefully the links below work because I am doing all of this from my crappy euro cell phone. Many thanks.

The bar seems to be in the right spot. What's probably causing this is the way you're cranking down your elbows as you descend. Your grip is collapsing at the bottom. Keep your chest up as you descend and come up. Your upper back should be locked by lifting your chest and keeping it up the whole rep. If you try that, it may no longer feel necessary to pull your elbows down.

Do you feel like you are putting a lot of pressure on the bar with your hands, almost as if you were trying to bend the bar across your back?

[Ronin]

Due to my arm/shoulder inflexibility there is some pressure, but not nearly enough where I would consider what you describe as trying to bend the bar over my back.

Do you always squat shirtless? The bar may be slipping a bit or feel like it's in danger of doing so, and you may be detecting that consciously or subconsciously and doing things consciously or subconsciously to prevent that. There's a reason why we tell people to squat in cotton (not synthetic) t-shirts as opposed to in just a tank or bra or shirtless.

[Ronin]

I never squat shirtless. It was only for the purpose of giving a more clear view of what's going on with the bar on my back. I figured the placement of the bar is what's giving me the arm pain and the loose shirt would obstruct the view.
But I do see your point.

[Gunnhild Bruno]

Good to know.

Can you provide a side view? It's generally kind of difficult to see everything that goes on from just one viewpoint.

[Ronin]

So today I decided to start with bench press and do squats last for the obvious reason. Except I could feel a bit of discomfort to begin with. On my second set the bar collapsed (on the safty) and I had to abandon the workout. My entire biceps were on fire and I had to sit in the gym for 30 minutes or so until the pain was managable enough to drive. I have been subjected to numerous painful situations before so my 1-10 scale is not as relative to others, but I'd rate it at a 5.5 at the very beginning. Thing is, it lingered for a while. I suppose it's tendonitis, but the majority of discussions on this board are on the elbow and I have no discomfort there.

I do have a side view video I took the other day, but I can't upload it just yet because I don't have high speed internet at the moment.

One thing that has me thinking..
when I pull my elbows back and up, it seems to push the rear shoulder up and the weight of the bar seems to be pushing down on the rear outside of the arm/shoulder. This leaves me leaning quite forward to keep the bar on my back. Am I wrong to believe this might be the source of the pain? I think I need to shrug it a bit harder and figure out how to build a more stable shelf back there.

Either way it's probably best to put up the side view video befor guessing what my problem is.

Thanks for checking in though, feels nice to have people genuinely interested in helping out.

Here is the side view. I realised I had already uploaded it.

I think your problem is actually far less complicated than originally thought.

The side view shows that you start off with the bar in the perfect spot, but as you kind of press yourself into the bar before you unrack, you end up with it a little bit low. Just by about half an inch or so, in my opinion, but that can make a difference.
