Good evening. My mom said she lightly hit her head last night. She was on her knees and lost her balance and hit her head on the base of a coat stand. There’s no bruise or current pain, but I did notice she got up later this morning and she was tired. She is currently back to normal, but she is recovering from a stroke from April 4 of this year. Should we be concern,,could a blood clot be an issue. Thanks for your assistance!
