What are the causes of arm pain and soreness?
I have been experiencing soreness in my upper limbs recently, especially after physical activities. Sometimes my arms feel weak, and I even have some difficulty holding objects. What could be causing this? Can overexertion lead to upper limb soreness?

Upper limb soreness is a common symptom that can be caused by various factors. The following are some common causes of upper limb pain:
1. Poor blood circulation: When the body is exposed to cold environments, blood vessels may constrict, leading to impaired blood flow. This can result in insufficient oxygen supply to the muscles and accumulation of metabolic waste, causing soreness in the upper limbs.
2. Muscle strain or overuse: This is one of the most common causes, especially after performing repetitive movements, lifting heavy objects, or maintaining the same posture for a prolonged period. For example, extended use of a computer, typing, or doing household chores can lead to muscle fatigue and soreness.
3. Muscle spasms: Muscles may become tense and spasm easily when stimulated. If the muscles remain in a state of prolonged stimulation, inadequate blood supply and nutrients may lead to soreness in the upper limbs.
4. Inflammatory conditions: Such as tendon sheath inflammation or myofascial inflammation. These inflammatory conditions may be caused by long-term overuse or poor posture. Inflammation and irritation can lead to muscle tension and pain.
5. Nerve-related disorders: Such as sciatica, cervical spondylosis, or carpal tunnel syndrome. These conditions can affect nerve function, causing pain, numbness, or tingling in the upper limbs.
If the pain persists or is accompanied by severe symptoms, it is recommended to seek medical evaluation at a hospital immediately.
