You really didn`t give us much of a story to go by. Are you having sex ? Was it protected by the use of condoms.? Your feet, knuckles , and chest have nothing to do with any STD or their symptoms. The red penis head may be just irritation or a yeast infection. The suggestion given earlier was wise. Any question you may have should be answered in a clinic that can examine you. Look in the phone book for your local health department , if you don`t have a Doctor. Take care.U
