Introduction
Severe pain in injured tendons at night may be caused by factors such as exposure to cold, overexertion, or myofascial inflammation. It could also be due to other conditions like rheumatoid arthritis. If the pain is severe, it is advisable to consult a doctor promptly to determine the underlying cause and receive targeted treatment. Additionally, adequate rest should be ensured and strenuous physical activities should be avoided.
Generally, severe pain in injured tendons or muscles at night may be caused by factors such as cold exposure, overexertion, or myofascial inflammation. Specific analyses are as follows:
1. Cold Exposure
If there is a significant temperature difference between day and night, the injured area may become exposed to cold, leading to local blood vessel constriction and spasms, which can worsen pain symptoms. Applying a warm towel compress to the affected area can promote local blood circulation and help alleviate discomfort.
2. Overexertion
If heavy physical labor is performed during the day, repeated strain on the injured area may aggravate the condition. It is recommended to reduce workload, and under the guidance of a qualified practitioner, massage therapy may be used to improve meridian flow and relieve symptoms.
3. Myofascial Inflammation
Myofascial inflammation may result from chronic strain, damp environments, viral infections, or other factors, causing aseptic inflammation in muscles and fascia. Patients often experience persistent dull aches, soreness, or throbbing pain, with symptoms worsening in cold weather or when fatigued. Treatment under medical supervision may include medications such as celecoxib capsules, diclofenac sodium sustained-release tablets, or eperisone hydrochloride tablets.
Besides the above causes, conditions such as rheumatoid arthritis, gouty arthritis, or septic arthritis could also be responsible. If pain is severe, it is advisable to consult a doctor promptly to determine the underlying cause and receive targeted treatment. Additionally, adequate rest should be maintained and strenuous physical activity avoided.
