Bleeding Under The Skin
Posted , 10 users are following.
I have purpura on my arms caused by bleeding under the skin. Most of them seem to be in long lines so look like I have been scratched by a cat while others vary in size from small dots to nearly a centimetre in diameter. They also itch and then sometimes break open, although the itching may be something else and the broken skin may be due to me scratching although I try not to. I have been on pred for PMR since January. Does anyone else have similar symptoms? My GP did not know what is causing it but plumped for the steroids. The purpura slowly fade and then new ones suddenly appear, one minute they are not there and the next time I look new ones have arrived. They are reddish to start with then fade and then disappear.

Does anyone get the bruises on legs, Some just seem to suddenly appear for no reason, or perhaps if I just brush pass something they appear,
I have found that there are other type illnesses where the symptoms are these purple marks on legs?
any info greatly appreciated.

I though when they appear out of the blue then it is called purpura. But mine only appear if I have knocked against something i.e an actually wound.

My GP calls it purpura. I think some of mine appear out of the blue but they are probably due to knocks and I didn't realise. I also notice they have started appearing if I scratch my arm for example, but they seem to be smaller spots.

I don't think that is necessarily a criterion - the term refers to spots that aren't a blanching rash and are due to bleeding from whatever cause:
"Purpura is a condition of red or purple discolored spots on the skin that do not blanch on applying pressure. The spots are caused by bleeding underneath the skin usually secondary to vasculitis or dietary deficiency of vitamin C (scurvy).[1] They measure 0.3–1 cm (3–10 mm), whereas petechiae measure less than 3 mm, and ecchymoses greater than 1 cm."
They can be due to various things but they are all haematomae and size is the main differentiation:
"Bruise, which is a hematoma caused by trauma
Petechia, which is a small type of hematoma (<3mm)
Ecchymosis, which is a large type of hematoma (>1 cm)"
