Back pain after a cold is common, mainly because a cold can cause chills and fever in the body, resulting in a systemic inflammatory response, leading to lactic acid accumulation in the muscles of the back of the lower back, which leads to back pain. When pain occurs, pay attention to the low back area to keep warm and avoid catching cold, and it is best to check the blood routine. If there is a viral infection, antiviral treatment is needed, you can take some anti-inflammatory painkillers appropriately, and drink more water at the same time. Muscle aches and pains do not need to be heeded, and the back aches and pains will disappear automatically after the cold has healed for some time, so don’t worry too much. If you still have the above symptoms after the cold symptoms are obviously controlled, other diseases such as lumbar spine lesions and lumbar strain can be ruled out by CT or MRI of the lumbar spine.
