I guess if it were my child, i would take him to a great chiropractor/osteopath (who does manipulations) for an evaluation and second opinion on the structural integrity. If they also find nothing anatomically wrong, acupuncture would be my next or simultaneous visit (you can do both without waiting on chiro/osteopath assessment).
I do not recommend using ice because, though it does stop inflammation, it does so by stopping blood flow. You want the opposite. You want to increase blood flow because the blood carries nutrients and other supplies your body needs to repair the damage in the area. Secondly, ice will tighten the muscles even further. If you find heat aggravates the pain, use something like icy-hot, mineral ice, or the white colored tiger balm instead. These topical treatments have the same anti-inflammatory effects as ice, but they actually increase blood flow through the area.
I would take your son to a physiatrist to check out the mobility of his shoulder, as certain movements might be worse than others. Check all this; a treatment plan can then be put in place. Physiatrists are medical doctors who help heal the body without surgery. He will be fine, but listen to him if he says it’s painful. I am old school where we did not rely on tests, X-rays, etc. We did a proper head-to-toe check and listened to the child. Two hands and ears are still the best equipment a doctor can possess.
Hugs for a happy child.
Has the pediatrician considered other causes besides the obvious ones? Sometimes the cause of shoulder pain can be referred pain from something else going on in the body. The Mayo Clinic website lists over 20 potential causes of bilateral (both sides) shoulder pain.
If no physical cause can be found, are there any challenges, like bullying for example, that your son has encountered outside the house that would cause him not to want to venture outside?
Maybe a more comprehensive physical/emotional health exam with blood work would be helpful. If the pediatrician defers further exams, then perhaps seek out another GP.
If you evaporate the moisture through the acupuncture, the ligament contracts and fixes the bone firmly, and the muscles are restored to their original state, and the pain disappears.
Go see a Licensed Acupuncturist and see if they can help - they have options beyond needling, such as "gua sha" (a scraping tachnique), cupping (a suction technique), Chinese massage, herbs, salves, patches, etc.
Find a licensed Acupuncturist in your area (and L.Ac. not a DC or MD who "does acupuncture). Find one who works with children and is good with muscle pain. Your son should be better soon, since the MD's already ruled out major problems.

I'm sad about your son's condition, but acupuncture and other adjunctive treatments should help your son. Find an acupuncturist near by.

The shoulder pain can be due to a growth spurt. Give it two days. If nothing changes, you can definitely try acupuncture, as long is your son is onboard with that. Acupuncture will provide relief from pain by moving blood and fluids around the shoulders
I'd suggest starting with the "Find a Practitioner" page at NCCAOM.org. Find some acupuncturists local to you and see if they offer a free initial consult. You're looking for someone both you and your son feel comfortable with.
Depending on your son's feelings about acupuncture, you might also try to find someone who can treat with fewer needles.
