One week after clavicle surgery, the feeling of ants pinching may be caused by mental tension, granulation tissue proliferation, trauma infection, etc. It can be treated by relieving tension and taking oral anti-infective drugs as prescribed by the doctor. 1. Mental tension: after clavicle surgery, some patients may have the feeling of ants pinching due to too much mental tension. You can do activities that allow you to be quiet, such as reading, listening to soft music, etc., to relieve tension. 2. Granulation tissue proliferation: One week after clavicle surgery, the feeling of ants pinching may occur due to the proliferation of wound granulation tissue. This is a normal phenomenon of wound recovery and does not require special treatment. 3. Wound infection: After clavicle surgery, due to the lack of good wound care, or wound bacterial infection, there will also be a feeling of ants pinching. The infected wounds need to be disinfected regularly with iodophor, etc., and treated with anti-infective drugs as prescribed by the doctor, such as cefixime and amoxicillin. One week after clavicle surgery with ant-pinch feeling, it is recommended to go to the hospital in time for follow-up, or consult with the surgeon, and under the guidance of the doctor to carry out the necessary treatment.
