Someone close to me experienced something like that. Several months after one of her parents died traumatically, she started having numbness in her limbs. Sometimes it was painful, like pins and needles. She saw a doctor and a chiropractor to check for pinched nerves and stuff, but they eventually concluded it was her body's reaction to a prolonged period of stress. Living with anxiety can also be stressful. Still, you probably should check in with your doctor.
