I fell on my side, primarily my shoulder a few weeks back and since then it has had a bit of sensitivity, like a mix of soreness and pain at times going from the outside center of my deltoid almost straight up and over to the top of my shoulder a couple inches past the end of the deltoid. It is uncomfortable to sleep on my side unless I carefully position my left arm, and certain lifts and exercises that require pressing overhead, lifting overhead out in front, and to some extend things like pushups and pull-ups. Sometimes it will start aching or throbbing a bit after substantial use.

It's very slowly improving but I'm using it quite a bit, which may be a dumb thing to do. My right side has similar symptoms but far less intense.

My guess is bursitis, but I do find it a bit odd I am getting it in both shoulders, so it may not be due to the injury, but rather my training. I don't feel and weakness or clicking or popping or anything like that. It's more like a nerve pain, not unlike when you bang your elbow and hit your ulnar nerve type thing.

Is my guess right or could it maybe be something else?

Most like subacromial impingement given description and assuming you are class of 98. This is technically just a collection of symptoms (with bursitis being one of the symptoms). It's not the "cause". Most commonly the reason is due to the way the scapula is moving (or not moving) during overhead movement, especially from about 60 degrees to 110 degrees of motion. Can also be caused by arthritic changes to the glenohumeral joint or shape of acromion. If it persists more than a couple weeks, find a good PT who can direct you in some possible adjustments in your activity. NSAIDs usually a good place to start. Check to see how your internal rotation is and look at functional IR stretches or "sleeper stretch" to improve IR of the shoulder. Injections, although effective, also can lead to long term issues with breakdown of the tendon causing increased risk of rotator cuff tears.

I havent watched the whole thing, but the intro explanation is fairly good at explaining. Google away at your own risk.

Thanks. Yeah, I figured I might end up at the PT. I've been doing some fairly intense training 5-6 days a week for about 15 years now so usually I am fine with some soreness and such but I haven't had this in a long time. Usually range of motion is not a issue for me, and I do a lot of stretching and mobility work, but that fall onto my side and particularly my left shoulder seems to have done a little damage.

No handstand walks for a few weeks.
