The bumps can be very itchy, can bleed if irritated, and the skin around them can become uncomfortable. If on fingers, they are sometimes confused with other problems such as fluid filled sacs (cysts) or bone spurs from arthritis.
A primary care physician or dermatologist are often the first physicians to treat this problem. There are many different treatment options. While it is very rare, it is important to know that a bump that does not respond to regular treatment can be a sign of a developing skin cancer lesion.
Treatments include simple solutions such as placing duct tape over the bump after rubbing it with a pumice stone. Other methods may include applying salicylic acid or liquid nitrogen to freeze the bump. If these methods do not work, a chemical called cantharidin may be used. Finally, surgical excision or biopsy might be indicated for bumps that do not seem to go away or are in areas that are hard to treat with other methods.
Perhaps the most important thing to remember during treatment is patience. Tried and true treatments generally work but take time.
