well, the doctor thinks its bedbugs...the swelling and itching have subsided.
Hi,
Differentials would be an insect bite, dishydrotic eczma, and herpetic whitlow to name a few.
I suggest you seek consult with your physician for a more definite diagnosis in case this may indeed be an insect bite and may need some antibiotics. The fact that this is itching may also point to a possible eczematous disease.
Wash your hands with a mild soap and avoid any sexual activity until a diagnosis has ben established.
Keep us posted.
