Everything Drnee stated is correct.
Don't be overly concerned at this point, because the issue could be as simple as a deficiency of B-12 and folic acid. These substances are sold together as a sublingual liquid, and it wouldn't hurt to buy some today.
One reason to have a comprehensive check-up is that there is a possibility - by no means a certainty - that the bleeding into the tissues might be systemic. That is to say you could be bleeding internally. Or if your blood isn't clotting, you could have a minor fall on the sidewalk and suffer a bleed inside the skull, with devastating results.
Often a physician can simply resolve a problem such as you have.
In other cases there are still interventions that can eliminate life-threatening complications.
Seeing your physician for a complete work-up should be "number one" on your list of "things to do".
Hi
Thanks for writing to the forum!
If you are not on any medications like anticoagulants or birth control pills then this could be due to clotting disorders, fragile spider veins, deep vein thrombus, deficiency of Vitamin B12, folic acid, or Vit K, a liver disease or certain cancers. It could also be due to pressure urticaria. If you are on medications then you need to discuss that with your doctor.
You need a comprehensive investigation taking all these points in consideration. It is difficult to comment beyond this without examining. Please discuss this with your doctor and get yourself investigated accordingly. Do let me know if there is any thing else you want to know. Take care!
