Minor infections of the skin around the nail (paronychia)

Q. I'm waking up every morning with little bites on my arms. Could
these be from bedbugs?
A. They certainly could be. Bedbugs -- small, oval-shaped, wingless
insects that feed on the blood of mammals (including humans) -- are making a

You may bump or catch an artificial nail, jar it loose from
your natural nail, and create a gap between the artificial nail and the natural

or a joint (septic arthritis). Infections may also affect the

Infection of the skin of the
fingertip (whitlow) can also be caused by a viral infection (herpes simplex) or a bacterial infection (felon).
Felon can cause destruction of large areas of tissue on the fingertip and also
cause symptoms that affect the entire body.
Felon caused by staphylococcal whitlow is usually
caused by traumatic injury to the fingertip. The end of the finger will be red,
hot, sore, and swollen. An abscess may form. Treatment involves surgery to
drain the abscess, plus antibiotic treatment. An X-ray of the finger is usually
done to determine whether infection of the bone (osteomyelitis) is
Felon caused by herpes simplex appears as blister
formation (vesicles). This occurs most often in people such as dentists,
doctors, or nurses who are exposed to infected oral or respiratory secretions.
Symptoms include intense itching and pain, followed by the formation of deep
sores. A similar problem may be caused by biting your nails while you have a
cold sore. This type of viral infection may respond to acyclovir. The use of
rubber gloves prevents this infection in health professionals.
