The skin of the thigh hurts when touched. In this case, the first thing to check is whether there are any abnormal manifestations of the skin on the thigh, such as whether there is redness or swelling, and whether there are some manifestations similar to dermatitis, surgical scabs or carbuncles. If not, then when this occurs, you need to consider whether the pain is due to muscle strain caused by overworking or excessive physical exercise. On the other hand, it is important to consider whether it is a manifestation of pain allergy, and on the other hand, it is important to consider whether it is caused by other reasons, such as lumbar spine pathology, sciatic nerve pain, etc. This situation needs to go to the hospital, under the doctor’s further examination to clarify the cause, for active treatment and prevention.
