Icheon Rotator Cuff Syndrome

When Nightly Aching and Tingling Make It Hard to Sleep


Hello.

This is Director Seo Se-wook of Kyunghee Yakson Korean Medicine Clinic in Icheon.

Patients who come to our clinic

for shoulder pain carry a heavy expression

from the moment they step into the exam room.

Having barely slept all night,

they have dark circles under their eyes,

and they gently cradle the painful arm

with the other hand.

Even when they sit down,

rather than letting the arm hang loosely,

they carefully rest it on their knee

— that is the kind of posture I notice.


Every time they roll over while lying down,

a sharp pain jolts them awake,

and their arm goes numb, so they get up at dawn

and shake it out — I meet people

like this every single day.

"Doctor, my shoulder aches every night,

so I wake up every hour."


"Doctor, when I lie on the painful side,

my arm goes numb and I can't fall asleep."


"Doctor, I even got injections,

so why does it get worse only at night?"

When I hear these words,

my heart grows heavy too.

Thinking it was just simple muscle pain,

many people endure it for months

before finally coming in — more than you'd expect.

Today's topic is precisely

Icheon rotator cuff syndrome.



When many people think of shoulder pain,

the first thing that comes to mind is frozen shoulder,

but in fact, a large portion of shoulder disorders

after the age of 40 start with

a rotator cuff problem.

There's one point I really want to emphasize here:

even among those who have been advised to have surgery,

if you find the exact cause and approach it step by step,

there are not a few cases

that can recover without surgery.

So today,

I'd like to address the three questions

that people who lose sleep at night

are most curious about.

First, why does it ache and tingle

so much more at night?


Second, do I really have to get surgery to recover?


Third, this shoulder that keeps flaring up once it hurts

— is fundamental treatment possible?

For those who struggle to fall asleep night after night

due to Icheon rotator cuff syndrome,

I hope this article serves as a small guide.


First, why does it hurt more only at night?

This is a part that puzzles many people.

During the day it was bearable,

but the moment they lie down to sleep,

the pain gets worse.

The reason is simpler than you'd think.

The rotator cuff consists of four small muscles

and tendons that wrap around the shoulder, and

when inflammation or a partial tear occurs here,

blood circulation slows in the lying position

and swelling builds up.


That's why, as the night deepens, the pain

becomes more distinct, and in many cases

arm numbness comes along with it.

At our clinic, for those who come in

with shoulder pain, we first perform an ultrasound exam.

The thickness of the tendon, whether there's a tear,

and the state of the swelling can't be known by feeling from the outside,

so we have to check them directly to set

the right direction for treatment.

Even among those who come from near Changjeon-dong in Icheon,

there are often cases where someone thought

it was just a simple stiffness, only to discover

a partial tear after the exam.


Second, is treatment possible without surgery?

This is one of the questions

patients ask most often.

To give you the conclusion first,

depending on the degree of the tear and your lifestyle,

you can recover fully.

If it's not a complete tear but a partial tear,

or a stage of inflammation or tendon degeneration,

returning to daily life with non-surgical treatment

is possible in many cases.

The treatment we provide

is broadly divided into three stages.

First, we calm the swelling and inflammation.

At this point we mainly use pharmacopuncture —

components extracted from herbal medicine —

checking the painful area with ultrasound

to treat it precisely.



At this stage, many people find

their nighttime pain becomes much more comfortable.

Next is the functional recovery stage.

Using acupuncture, electroacupuncture, and large moxibustion together,

we loosen the stiffened surrounding muscles

and aid blood circulation to help tissue recovery.

As needed, we may also carry out bee venom pharmacopuncture, cupping, and physical therapy

together.

Last is the relapse prevention stage.

With herbal medicine suited to your constitution,

we enhance the recovery capacity of the muscles and tendons,

and we also teach you simple posture correction.


Third, why does it keep coming back?

The reason rotator cuff syndrome relapses so easily

is mostly because the pain is only briefly suppressed and that's the end of it.

Even if an injection temporarily presses down the inflammation,

if the damaged tendon doesn't recover,

the same spot hurts again a few months later,

and the nighttime pain returns as well.

That's why I emphasize treatment that goes all the way,

starting from swelling relief through

functional recovery to relapse prevention.


It's especially well suited to people like these.

Those who use their arms a lot,

such as in restaurant work or cleaning;

office workers who work long hours

hunched at a computer with rounded shoulders;

those over 40 who enjoy

golf or tennis;

and those who haven't been able to sleep

for a long time because of nighttime pain.


To sum up today's talk, here it is.

A shoulder that aches and tingles more at night

is in many cases caused not by simple muscle pain

but by tendon damage and swelling.


If the degree of the tear isn't severe,through pharmacopuncture, acupuncture, and herbal medicine,

recovery of daily life is possible even without surgery.


To prevent relapse, a step-by-step approach

that continues from swelling relief through

functional recovery to relapse prevention is absolutely necessary.

If Icheon rotator cuff syndrome

has made it hard for you to fall asleep night after night,

please don't endure it alone — come see us once.
