Dark red rash on legs causing anxiety - skin infection?

It seems like you are going through mastitis which is an infection in the breast tissue. The pus-like discharge is a sign of infection. Mastitis can result from bacteria entering the breast via a cracked nipple or blocked milk duct. It is important to keep on taking any prescribed antibiotics and not to squeeze the breast because it can make the infection worse. Ensure you feed and pump frequently in order to clear the infection. With proper treatment and rest, mastitis can generally be cured within a week.

I can see that scratching you due to a street dog can be a worrying issue for you. From your information, the scratch is not too deep, which may mean there is a low chance of infection. Watch out for any redness, swelling, or warmth around the area. First of all, wash the scratch using soap and water and then apply the antiseptic cream to the area to avoid any further infection. Watch the scratch for a few days, and if you spot any of the infection signs that are getting worse, like more pain, redness, or pus formation, it is better to go to a doctor.

You might have a skin condition known as tinea cruris, or jock itch. This is a fungal infection that often affects the groin area.

To treat it, it is important to keep the area clean and dry, wear loose clothing, and use antifungal creams.

HIV does not spre­ad easily from dried blood. The virus die­s quickly outside the body. A small cut touching dried blood is ve­ry unlikely to cause infection. Unbroke­n skin protects against HIV entering the­ body. Being cautious with blood is wise. Howeve­r, in this case, the chance of ge­tting HIV is extremely low. It's still good to watch for any unusual symptoms. But you probably have­ nothing to worry about!
