Be seen today
Seek urgent same-day medical assessment if you develop a fever, shaking chills, or suddenly feel significantly unwell.
State clearly that you have had your spleen removed.
One-sided leg swelling or pain needs prompt assessment for a possible clot.
A bite from a dog or cat also warrants prompt medical advice.
