A sudden severe headache, confusion, weakness, or other neurological symptoms after an injury also requires urgent assessment.
The exact response depends on the circumstances.
When in doubt about severe or rapidly worsening symptoms, seek emergency medical assistance rather than waiting for an online explanation.
## Don’t Ignore Medications
One of the most useful questions to ask when unexplained bruising develops is:
**“Have I started taking anything new?”**
Medication-related bruising is common enough that it should be considered.
People taking medicines that affect blood clotting may naturally notice more bruises.
Some medications can also interact with one another.
If you take several prescriptions, over-the-counter medicines, or supplements, tell your healthcare professional about all of them.
Do not discontinue blood-thinning medication without medical advice.
The risk of stopping some medications suddenly can be greater than the risk associated with the bruising itself.
## Nutrition Can Also Matter
Nutrition is another possible consideration.
Certain nutritional deficiencies can affect blood vessels, skin, or the body’s ability to maintain normal blood clotting.
However, taking large doses of vitamins or supplements simply because you read about bruising online isn’t necessarily helpful.
If a deficiency is suspected, a healthcare professional can determine whether testing is appropriate.
Treatment should be based on the actual cause rather than guesswork.
## Keep Track of Changes
If you’re concerned about unexplained bruises, keeping a simple record can help.
