Ice is better for shoulder pain when you have new, sharp shoulder injuries with swelling.
Heat is better for shoulder pain when you have long term stiffness and tight muscles.
You should use ice for shoulder pain with new shoulder injuries and shoulder injuries that have swelling and inflammation and after any activity that causes shoulder pain.
Apply ice within the first 48 hours to 72 hours of a sudden injury, strain or sharp flare-up.
Ice is good for swelling and inflammation as cold from the ice narrows blood vessels to lower swelling and numbing sharp pain.
You should also use ice after exercising or heavy physical work that irritates the shoulder.
You should use heat for shoulder pain when you have chronic shoulder pain or stiffness and before any movement.
Just avoid heat on new shoulder injuries as heat increases blood flow and can make fresh swelling and inflammation worse.
You can also apply a warm towel or take a warm shower to loosen a stiff shoulder before stretching or moving and use heat for dull, lingering aches or tight muscles after the first 72 hours.
When applying ice or a heating pad, just make sure to use a barrier, by applying the ice or heating pad in a clean towel or cloth and never place the heating pad or ice directly on bare skin as it can cause burns with the heating pad and frostbite with the ice.
And limit the time, and only apply the heating pad or ice for 15 to 20 minutes at a time and take breaks, by waiting at least an hour between sessions and never fall asleep with the heating pad on.
A red flag in shoulder pain is when the shoulder pain comes with chest tightness, shortness of breath, dizziness, or pain that spreads to your jaw or neck as it can signal a heart attack.
Urgent medical emergency warning signs of shoulder pain include having pain that is accompanied by shortness of breath, sweating, or dizziness.
Signs of infection, such as having a joint that looks red, feels very hot to the touch, or has severe swelling and fever.
Trauma and deformity, such as sudden severe pain after a fall, accident, or a visible change in the shape of the joint.
And neurological loss, like sudden numbness, a complete lack of feeling or pins and needles feeling that does not go away.
The signs that you should see a doctor soon if you have shoulder pain include having any constant rest pain and discomfort that wakes you up at night or hurts while lying down.
Systemic issues, like unexplained weight loss, night sweats or a persistent fever.
Severe weakness, which includes an inability to lift everyday objects or your arm dropping suddenly.
And no improvement, where you have pain that does not get better after one to two weeks of rest and home care.
You can also often tell if your shoulder pain is muscular by the symptoms as shoulder pain that is muscular feels like a dull and achy soreness that gets worse when you move the muscle, but leaves the joint strength and range of motion mostly normal.
Signs of joint pain being muscular include surface tenderness, achy sensation, temporary relief occurs and it gets better at rest.
When your joint pain is muscular, the pain often fades when you stop moving and allow the muscle to rest.
And warm showers, gentle stretches, or light massage help the fibers feel better and the discomfort feels like a burning, throbbing or dull ache after heavy work, exercise or bad posture and you feel pain when you press directly on a tight knot or specific spot on the tissue.
The signs that your shoulder pain is not muscular include you have joint and tendon issues, nerve problems and severe tears.
Sudden weakness or an inability to lift your arm can mean that you have a rotator cuff tear.
Having pain that shoots down your arm or comes with numbness and tingling, often begins as a pinched nerve in your neck.
And having pain that stays constant even when you rest, or makes a clicking and grinding sound, often points to a joint or tendon problem.
Common conditions that also start with shoulder pain include rotator cuff tendinitis, frozen shoulder (adhesive capsulitis), Polymyalgia Rheumatica and Cervical Radiculopathy.
Rotator Cuff Tendinitis or Impingement, results from inflammation of the tendons or bursa in the shoulder that often starts as a mild, dull ache when lifting the arm or reaching overhead before turning into sharper pain.
Frozen Shoulder is a condition that often begins with a gradual, deep aching pain that restricts movement before severe joint stiffness sets in.
Polymyalgia Rheumatica is an inflammatory disorder, which commonly causes sudden, symmetric pain and morning stiffness in your shoulders and hips.
And Cervical Radiculopathy, involves a pinched nerve in your neck that frequently radiates pain, numbness or tingling directly into your shoulder.
The most painful shoulder condition is frozen shoulder also known as adhesive capsulitis.
Frozen Shoulder is when the capsule that surrounds the shoulder joint thickens, tightens and forms scar tissue.
The initial "freezing" stage of frozen shoulder brings constant, deep, and worsening aches which disrupts sleep and severely restricts movement.
Another most painful shoulder condition is calcific tendinitis.
Calcific Tendinitis is when calcium deposits build up inside your rotator cuff tendons.
And when these calcium deposits enter an inflammatory phase, they cause sudden, severe and blinding pain, which can make any movement of your arm nearly impossible.
Another most painful shoulder condition are fractures.
Acute traumatic injuries, like a broken collarbone or proximal humerus fracture, cause severe mechanical pain, although they also stem from structural breaks rather than chronic disease processes.
Severe Bursitis can also cause severe shoulder pain.
Severe Bursitis is a result of extreme inflammation of the fluid filled sac cushioning the joint.
Other conditions that can cause severe shoulder pain and shoulder pain in general include pinched nerve or cervical radiculopathy, brachial plexus injury, heart attack and gallbladder or digestive issues.
Referred pain from internal organs can cause severe discomfort that can be felt around your shoulder blade.
Sudden, severe pain, which is frequently in the left shoulder or arm can signal a cardiac emergency, especially if accompanied by chest pressure, shortness of breath or nausea.
Brachial Plexus Injury, results from damage or stretching to the network of nerves that run from the neck through your shoulder.
And Pinched Nerve or Cervical Radiculopathy, results from a compressed nerve root in the neck sending sharp, burning pain down into the shoulder.
And even a dislocated shoulder can cause shoulder pain.
When you have a dislocated shoulder, the top of the arm bone popping out of the shoulder socket, causing intense pain and a locked joint.
