Ive got severe itching on my legs which is worse at night.bern waking up in night with bad pains in calves & been rock hard & unexplained bruising?

See your doctor: If it was just nighttime itching, I would think you have restless legs syndrome. But adding the other symptoms makes me highly suspicious of a vascular problem. Unexplained bruising itself deserves a full work up and may or may not be related. Please see your GP asap. He will direct you to the right tests and specialists if needed.
