If you wake up in the morning after breastfeeding and can’t stretch your fingers, it may be caused by improper breastfeeding posture, tenosynovitis, cervical spondylosis, etc. Breastfeeding patients can improve their symptoms through general treatment and physical therapy. 1. Improper breastfeeding posture: If breastfeeding for a long time sitting or lying on the side, it may lead to compression of the nerves in the hand, thus leading to the inability to extend the fingers. Women should maintain the correct breastfeeding posture, avoid holding the baby for a long time, and massage or apply hot compresses on the hand as appropriate to alleviate the symptoms. 2. Tenosynovitis: For tenosynovitis patients should pay attention to rest, reduce the activity of the lesion, can use equipment to fix the affected limb to provide protection. As it is not suitable to use medication during breastfeeding, ice or heat packs can be applied under the guidance of the doctor, but care should be taken to ensure that the temperature is appropriate. 3. Cervical spondylosis: For women with cervical spondylosis during breastfeeding, they should improve their bad living and working habits, avoid overwork, and do daily exercises for the shoulder and neck. Physical therapy can also be carried out through ultrashort wave therapy, ultrasound therapy, high potential therapy, phototherapy and ultraviolet therapy to alleviate the symptoms. It is recommended that breastfeeding women pay attention to rest, avoid overwork, and pay attention to changes in the condition, and seek medical treatment if there is any abnormality or if the symptoms continue to worsen.
