Some people really do just bruise easily. If you're really worried about it, I'd see a general practitioner to rule out anything weird.

Saw your post while looking for another subject. My wife bruise easily too (even when the wind blows!). anyhow I know I am not suppose to recommend specific products but I'll risk it here, do a search for BruiseMD. My wife has been using it for 3 months and loves it. Hope this helps.

Have you had blood tests done to confirm that you don't have iron deficient anemia? If you have this, when you are on your period, because you are losing blood, it causes you to bruise more easily and makes you feel fatigued. It is a simple blood test that counts the level of hemoglobin in the blood. It is called hematocrit. Generally for a woman, a normal hematocrit ranges from 38-46%. For example, if your hematocrit is 25%, that means that there are 25 milliliters of red blood cells in 100 milliliters of blood. If you are iron deficient, your hemoglobin will be less than normal. A simple fix for this is to take Ferrous Sulfate, the simple iron pill, found in most grocery stores. I take iron pills because that time of the month is so heavy, it causes my hematocrit to drop. This can happen in some women.
