Hello Cahamon,I have a feeling looking at the symptoms of itchy skin lesions bothering all three of you ,that all of you are manifesting symptoms of a skin infestation called Scabies
.Presence of pus dots suggest infection or may be severe inflammation.
You should see a Skin specialist( A Dermatologist
). An anti-scabies skin cream ,anti-histaminics to treat itchiness and/or an antibiotic based on the doctors discretion should rid all of you from this nasty but curable condition.Take care.
