Patient – Subungual haematoma


Often very painful, a blood blister under your toenail will cause swelling and bruising under and around your toenail.

How did I get this?

Usually a result of trauma, you may have stubbed your toe, dropped something on it, or been stood on.

You may also see this condition after endurance events e.g. running or hiking, or after wearing shoes that sre too small.

If you are taking anticoagulant medication you should take extra care.

What can I do about it?

Painkillers may help, but avoid those containing anti-inflammatories such as ibuprofen.

Piercing the toenail to release the pressure will give immediate relief, but this should be carried out by a medical professional if possible.

What help can I get for this?

Your Doctor or Podiatrist will carefully release the pressure and fluid from beneath the toenail, and advise you on appropriate dressings.

Your podiatrist can help if the toenail comes loose, or is not growing properly.

When will it get better?

Releasing the fluid from beneath the toenail usually gives immediate relief. Sometimes you will lose the toenail, but it should grow back again.
