Red spots on the soles of the feet are not necessarily syphilis. Because there are red spots on the soles of the feet, in most cases, it may be a symptom due to eczema, especially for acute eczema, there may be scattered red papules on the soles of the feet area, so it looks like red dotted spots, but it is more different from the syphilis rash caused by syphilis. If a syphilis rash is present, it manifests itself as a rose-colored erythematous base on the soles of the feet accompanied by mild scaling, and there are no obvious self-conscious symptoms, neither pain nor itching. If you want to determine whether it is syphilis or not, the most reliable way is still to need to be tested for syphilis antibodies, which requires a blood test. Therefore, the two also need to be treated carefully separately, as some fungal infections can also present with red papules on the soles of the feet.
