Why do I get sudden bruising on my legs without injury?

Hi,

Welcome to icliniq.com.

I understand your concern.

Easy bruising is not an uncommon complaint and has multiple causes. As a baseline, you would need to undergo a panel of investigations to determine the status of your bleeding and clotting profile. Reasons can vary from simple normal skin tendency to vitamin C deficiency, excessive and prolonged use of steroids (even a few inhalers for asthma have a combination with steroids), and mental stress.

A few appear like striae too, so kindly review if you have similar lesions on your lower abdomen, arms, and thighs (attachment removed to protect patient identity). Do not panic, even though the bruises appear alarming, and go ahead with the basic investigations suggested below.

Before deciding, this needs to be diagnosed:

• Complete hemogram with peripheral smear.
• Bleeding and clotting time.
• Prothrombin time.
• APTT with INR (activated partial thromboplastin time with an international normalized ratio).

The following condition needs to be ruled out:

1. Gardner-Diamond syndrome (a rare condition with painful bruising).

2. Long-term use of steroids.

3. Normal skin tendency.

I would suggest the following measure:

Thrombophob ointment (Heparin Sodium) for local application twice daily.

I hope you are satisfied with my answer. For further queries, you can consult me at iCliniq.

Thank you.
