The contact dermatitis can last a long time. It depends upon the nature, frequency and duration of the exposure to the allergens. If the exposure to the allergens continues it might take very long time. If the exposure to the allergens is stopped then it will be recovered quickly.

Your wife is likely to have an infection at the injection site. The symptoms such as heat, pain, and redness are caused when the bacteria get in. The area needs to be cleaned gently and the healthcare provider must be consulted. Antibiotics may be recommended to eliminate the infection. Do not use ice or cover it up without advice as it may aggravate the problem. 

The likelihood of HIV infection is negligible if a diabetic needle pricks your hand. HIV is transferred via blood, however, the needle prick is not a high-risk exposure. If you are concerned, watch out for symptoms such as flu, fever, or rash. If you see them, go to a doctor. 

Acrylic nails aren't recomme­nded before tonsille­ctomy surgery. Those fake nails could harbor ge­rms, making hand hygiene tricky. During tonsillectomy, doctors re­move tonsils, often due to infe­ctions or breathing issues. Clean hands pre­vent surgical site infections, so natural nails are only for this proce­dure. Wait until you've recove­red fully before ge­tting acrylics again.

Herpe­s is a common virus. It causes itchy, painful sores. The­se blisters often appe­ar around your mouth or private parts. You can get it through close contact.

Acne is one of the most prevalent skin problems, and it can be treated in several ways. For an accurate and tailored treatment plan, it is advisable to visit a dermatologist.

Since you missed tetanus vaccination after second-degree burns, you are at risk for tetanus infection. The symptoms may be visible within 3 to 21 days, usually at 7 to 10 days. Tightness of muscles, spasms in the jaw, and difficulty in swallowing are some of the symptoms that one may experience. If you notice these signs, you should seek medical attention at once. The tetanus vaccine can, however, be administered after an injury to avoid infection.
