When doing lateral raises, my left shoulder makes a clicking/ticking sound. It seems like the muscles of my upper extremity are rubbing against each other, and sometimes they are in a knot, and when released, the sound is made. My left scapula is slightly "winging" because of a rib hump due to left thoracic scoliosis (It's pretty mild. Can't remember the angle, but orthopedists advise against surgery or braces. I am a guy if that matters.). The clicking sound is less, sometimes disappearing totally, when I do a front shoulder raise. It is prominent when I do a lateral raise. I do not feel pain from this clicking/ticking.

I also have a sound when I do the lateral raise on my right shoulder, but it's softer.

(The same sort of sound can be heard when I do a squat. I have difficulty putting my feet /ankle completely on the floor when I do a squat.)

I am not asking for a diagnosis. Rather, I'd just like to know how likely it is that this sort of thing will attenuate muscle hypertrophy. I've been following muscle growth workouts for many months, almost a year, but I see very little growth in my deltoids, and triceps. My biceps and pec major grow much better. I'd like to know if, my safety and muscular health, and risk of injury aside, the lack of muscle growth in the tricep and deltoid vs pec major is possibly due to this clicking sound. (I do workouts for each muscle and give equal attention to each: lateral raise for deltoid, tricep skull crusher for tricep, pec flies for pec major, but I only really see growth in the pec major.)

Also note: (1) I watch my nutrition and calculate my macros, and follow the requirement faithfully. (2) I do make an effort to have sufficient sleep. (3) My testosterone is normal, I just did a blood test. (4) I do workout to fatigue and do progressive overload. I do feel sore but not very much and usually have recovered by the next morning.

I find it a little strange and am spending massive efforts "debugging" this issue.

Note I am also not asking for a definite answer, but just a best educated guess. I'd like to know your reasoning also, so do explain it.

Also, if you do not mind, what kind of condition is this mostly likely going to fall under? I searched a lot of stuff on Google Scholar, and in sports medicine books, Elsevier, Human Kinetics etc. I cannot seem to find a relevant or any closely related condition. eg. See the contents page https://books.google.com.sg/books?id=w8A0DwAAQBAJ&printsec=frontcover&dq=shoulder+clicking+sound&hl=en&sa=X&ved=2ahUKEwjfwpz9qdXwAhXEIbcAHb0yBj4Q6AEwR3oECCAQAg#v=onepage&q&f=false. I can only seem to guess that this is a shoulder instability condition? (Please ignore this last paragraph if this is something you must "diagnose".)

    Just a thought : You may just be unconsciously going a little easier on the areas that worry you, leading to less growth, or doing the movement wrong which might be causing the sound and reduced gains.
