Hello Mam, Thank you for visiting askmedicaldoctor.com. Bruising usually occurs due to rupture of tiny blood
vessels in the skin leading to appearance of tiny pinpoint red dots in the skin. Usually bruises heal within 2
to 4 weeks, and in healing process they often turn color from red to brown or purplish black. Most bruises may
come and heal away on their own. Home treatment may help speed-up the healing and relieve the pain and
swelling that often come with bruises that are caused by injury. Unexplained bruising though requires medical
evaluation to detect the cause as it may be a sign of any other bigger unidentified ailment. Still, it is said
that bruising easily does not always signify any serious health problem, especially if bruising is minimal or
has happened only once in a while. Unexplained bruising may occur due to any trauma which may not be recalled,
allergic reaction to any cosmetics or drugs, viral or other chronic infections that may build-up toxins in the
blood and tissues , deficiencies of vitamins B12, C, or K, or folic acid, decrease in platelet count
(thrombocytopenia) of blood due to some known or idiopathic reasons, inflammation of a blood vessel(
vasculitis), use of anticoagulants like warfarin, heparin, aspirin or steroids( now a days commonly used in
cosmetic purposes), bleeding disorders like hemophilia etc, chronic subclinical illnesses like liver, lupus
etc and leukemia ( in old age). You can take help of your doctor who can evaluate your family history of blood
disorders, clinical examination of petechiae, and conduct complete blood cell count( for evaluation of
platelets and ruling out any chronic infection), bleeding and clotting time, hemoglobin, any drugs you may be
using, allergy and tourniquet (petechiae) test to reach to diagnosis and treatment thereafter. Until then you
should take rest, apply ice on affected part for 10-20 mins 3 times a day, and keep your legs elevated from
heart level to reduce blood supply. Take a balanced diet esp. rich in vitamins like green vegetables and
fruits. You may use arnica as natural product for topical application. Do not smoke or use alcohol as these
may delay healing. Hope this information helps you and do keep us posted in case of any further doubts. Take

Welcome to the forum. The various causes of unexplained bruising without any other medical symptoms have been
very well explained by Dr Anurag. Anemia and deficiency of vitamins C, K, B12, or folic acid are the common
causes of easy bruisability. Try taking iron tablets and multivitamins for some days and see if the symptoms
improve. If the condition persists then the other causes enumerated by Dr Anurag have to be evaluated. One of
the other possibilities that can cause circular bruises type rashes on skin especially the legs and arms is
lichen aureus. It is a skin disease of children and young adults and may present as golden brown lesions that
may affect any part of the body. A complete blood count and skin biopsy are the diagnostic tests needed. The
other possibility that comes to my mind is of pityriasis rosea but in this the trunk is more commonly
involved. My sincere advice is to get all the possibilities enumerated by Dr Anurag as well as these
possibilities evaluated. I sincerely hope that helps. Take care and please do keep us posted in case you have
any additional doubts. Kind regards.

I have been having unexplained bruising for roughly 2 months now, sometimes they range from quite large dark
bruises on the back of my legs to small finger print marks on my arms like somebody has grabbed hold of me
extremely hard, the large bruises can hurt when you touch them. I am 38 years old an had nearly a full
Hystectomy just over a year ago leaving just the womb in, the only medication I take is HRT, I went to the
doctors just over a month ago regarding another issue and was advised to go back for blood tests if they were
still appearing, my imune system also seems low and I catch any bugs going round, could this be serious???

Bruises on arms for no reasons can be due to deficiency of iron, vitamins C, K, B12, or folic acid, liver
disease, aplastic anemia, SLE, bone marrow disorders or leukemias.

Jadera drug which is used as diet pills are composed of herbal extracts and are not FDA approved. They are not
safe to take and may cause insomnia. Nothing is known whether it causes increased bruising.

Bruises on arms without reason can be due to anemia, deficiency of vitamins, liver disease like hepatitis,
aplastic anemia or leukemia. Get a complete blood count, hormone levels and a bone marrow aspiration done.
