Should i be worried about my subdural heamatoma returning?

Subdural hematoma: Need more information. How did you get subdural hematoma ? By fall, trauma, car accident or blunt skull injury? How large was this? Was evacuation done? Was it slow and small bleed subdural hematoma and resolved it self? In all cases you have to see your neurosurgeon periodically with possible ct scan at intervals and discuss the recurrence rate in your specific case. Thanks.

Probably not: It should not be an issue unless you suffer head trauma or are taking blood thinners.

Yes: Subdural hematoma is a very serious condition. I am not sure how you can tell it is recurring, but if you feel the same way you did when you had it, you need to go to the hospital asap.
