I've 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?

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. ...Read more

What could cause levido reticularis to appear around knees for days straight in warm climate with unexplained bruising around legs in young adult fm?

Many possibilities: Livedo reticularis is a symptom rather than a disease. It can be signs of alternating dilated and constricted blood vessels as a reaction to temperature variations.

In either case you need to see a dermatologist and/or rheumatologist asap. ...Read more

I have multiple unexplained bruising on my hip and leg (one side) as well as leg aches and fatigue, on prednisone 20mg a day for a week, is it linked?

I have multiple unexplained bruising on my hip and leg (one side) as well as leg aches and fatigue, on prednisone 20mg a day for a week, is it linked?

Probably related: Prednisone makes the skin and blood vessels fragile, so much more prone to easy bruising with normal daily activity, for example if you sleep on the side where the bruising is. Muscle aches and fatigue can also be related either to the Prednisone itself, or to whatever condition the Prednisone is being used to treat. If the leg is also swollen, see your doctor to be sure it's not a blood clot. ...Read more

Unexplained bruising all over body, fatigue, wieghtloss, headaches, loss of appitite, body aches, mild dizziness, weak legs. What going on with me?

Something of concern: We get questions about "a bruise" all the time...those are not this much of an issue:
Generalized bruising
Weight loss

The other symptoms are hard to characterize (body aches/weakness/mild dizzy) since very common and usually from minor things.

The degree of both of the concerning symptoms I cannot tell without an exam for your situation. But deep/bloody bruising worse but exam/tests regardles ...Read more
