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.

Acrylic nails aren't recomme­nded before tonsille­ctomy surgery. Those fake nails could harbor ge­rms, making hand hygiene tricky.

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.

The tetanus vaccine can, however, be administered after an injury to avoid infection.
