Brief Answer:
Senile purpura that can be treated easily.

Detailed Answer:
Hello,

Thanks for writing to Health Care magic, I am Dr , Muhammad Ahmad , I have read your question closely, I understand your concern and will be helping you with your health related problem.

These bruises you are talking about are called purpurae (plural of purpura). If you never had history of such issues since your 40s and 50s then most probably this is senile purpura you are having, this means that with the passage of age , blood vessels of your skin keep getting weaker and weaker and eventually they start to break up with very minor touches and blood oozes out of them into the surrounding skin.

This usually happens around and after the age of 70 but might happen earlier depending upon life style, occupation and general health of the person.
Other cause of having a purpura can be blood thinners , if you are using any medication for blood thinning like aspirin specially, it can thin up your blood so much that it oozes out in skin forming bruise.

What you can do is that you should focus on using vitamins more, the best source is food obviously, citrus fruits are very very good for you as they have vitamin C which is essential to strengthen skin and vessels, vitamin E is needed too, to save you from oxidative injury, you can use an OTC multivitamin like Centrum to get essential vitamins and minerals.
If you are using blood thinners then notify your doctor about bruises. In your next visit to doctor do discuss these bruises with him he might like to get some specific tests done like platelet concentration, Bleeding time, clotting profile, scratch test, to see what might be wrong.
It is not an emergent situation though I would suggest you not to panic and start using vitamins helpful to strengthen your skin.

I hope this answered your question, If you have more queries I am happy to answer you.
Regards.

Dr.Muhammad Ahmad
