blood clot

when someone grabs arm to hard can it cause blood clot

[Dr. Kokil Mathur]

Hi!
Usually not, unless the grip was really hard and bruising or you are prone to easy bruising due to fragile blood vessels or certain medications or diseases. Usually you will have pain and soreness for some days and then you will be fine. However, if  a bruise has formed or there is undue pain, please consult a doctor. Take care!
