Welcome to H C M.
Your skin seems dry, i.e. xerotic.
You are likely to have pruritus
Extreme pruritus may provoke ecchymoses.
The cause of xerosis may be found out.
It may be hereditary or secondary to some condition.
Atopic diathesis, thyroid
dysfunctions,DM,anaemia, vitamin deficiencies, malignancies, blood diseases...etc may be ruled out.
For that, you consult dermatologist
Local moisturiser cream or lotion may be applied after bath.
Steroid cream may be applied at night.
Antihistaminics and oral steroids
in tappering dose may be taken till, relief you get.
I hope you got my answer.
