A common sign of nerve compression — if it appears after an injury or after a cast is applied, be especially cautious; see the warning signs section below.
Suggested Department
Orthopedics (bones/joints — NOT cosmetic surgery)Neurology (non-surgical brain/nerve conditions)
Common causes include exercise, dehydration, and calcium deficiency.

力が入らない
手（足）に力が入りません。
て（あし）にちからがはいりません。
I can't put any strength into my hand/leg.
If it comes on suddenly and is accompanied by facial or one-sided body symptoms, be alert immediately — refer to the related warning signs under the head section.
Suggested Department
Orthopedics (bones/joints — NOT cosmetic surgery)Neurology (non-surgical brain/nerve conditions)
Common causes include prolonged posture and muscle fatigue.
Suggested Department
Orthopedics (bones/joints — NOT cosmetic surgery)Osteopathic/chiropractic clinic (not medical; for reference only, cannot replace a doctor's diagnosis)
For everyday shoulder stiffness, an osteopathic/chiropractic clinic is fine for relief, but it's not run by licensed doctors and can't give a medical diagnosis. If numbness, radiating pain, or headache occurs, go to Orthopedics at a hospital instead
If there are blisters, a large area, or the burn is on the face, hands, or joints, it's best to see a plastic/reconstructive surgery department to reduce scarring risk. If there's confusion or possible smoke inhalation, call an ambulance immediately.

Suggested Department
Plastic Surgery (wound/scar care, e.g. moderate-severe burns)Dermatology
For blisters, large areas, or burns on the face/hands/joints, Plastic Surgery is recommended to reduce scarring risk; if there's confusion or suspected smoke inhalation, call an ambulance immediately
Severe pain, obvious swelling, and the shape looks different — possible fracture.
Severe pain plus swelling plus deformity plus intense pain on movement is a classic combination for a fracture — get an X-ray promptly and never try to reposition it yourself.

Suggested Department
Orthopedics (bones/joints — NOT cosmetic surgery)Emergency / Call ambulance (119)
After my cast/splint was applied, the pain is severe and painkillers aren't helping.
May be a sign of compartment syndrome, a true orthopedic emergency — delay can lead to serious, lasting damage to the limb. Contact a hospital immediately; don't wait for your next scheduled appointment.

Emergency / Call ambulance (119)Orthopedics (bones/joints — NOT cosmetic surgery)
A warning sign of a too-tight cast/bandage or compartment syndrome, indicating blocked blood flow — contact the hospital immediately; don't just wait and watch.

Along with shoulder stiffness, my arm feels numb and the pain is spreading.
Simple shoulder stiffness can be eased at a chiropractic/judo therapy clinic (seikotsuin), but if it comes with arm numbness, radiating pain, or headaches, it may point to a cervical spine problem. Judo therapists at these clinics can't make a medical diagnosis, so it's better to see an orthopedic department at a hospital (and a neurology department if needed).

Suggested Department
Orthopedics (bones/joints — NOT cosmetic surgery)Neurology (non-surgical brain/nerve conditions)
Shoulder stiffness alone can be relieved at an osteopathic clinic, but when combined with numbness/radiating pain/headache it may signal a cervical spine issue — see Orthopedics at a hospital (or Neurology if needed), not just an osteopathic clinic
