<s>[INST] I have a bunch of bruises on my legs and arms, which I can t totally account for. I took a pretty good fall and the pool last weekend where I twisted my ankle when they all started showing up. I only twisted my ankle. My ankle is only mildly bruised. Following this by a 3 or 4 days later I got a severe cramp in my calf muscle in the middle of the night and for the past two days my calf has been hurting. Is this something I should follow up with my MD? [/INST] Hi, Bruising and calf pain following injury may be due to calf muscle strain with bruising.
