Petechiae on lower legs???
Hi! I've had petechiae & some purpura on my lower legs for a couple of months now. It get worse when I'm on my feet/walking etc. I had gone to the ER and had tons of blood work, lung X-ray & leg ultrasounds- I do not have any clots. I'll be seeing a hematologist but not for at least a week. Any ideas???? Now, recent history DOES include a pulmonary embolism, but that has been resolved before petechiae, and that had been provoked after a car accident- I have never had a DVT. I have fibromyalgia.

@nanke99, this sounds concerning for you. Fellow members @phyllis731 @longlostbrat @beanglow have experience with petechiae and may have some thoughts and experiences to share.
I'm glad that you've been to the ER to rule out any causes that may require urgent care. I hope you'll learn more at your upcoming appointment with a hematologist. I'll be anxious to hear the results of your appointment.

3 ReactionsIn 2021, following a confirmed infection with the SARS-CoV-2 Delta variant, I developed petechiae.
Subsequent medical investigations confirmed von Willebrand disease type 2 (VWD type 2) and Factor V Leiden, findings that had previously been indicated by genetic (DNA) testing. I was subsequently evaluated by a rheumatologist and underwent further laboratory investigations, including ELISA-based blood testing.
At that time, cutaneous manifestations associated with COVID-19, particularly petechiae and other purpuric eruptions, were not yet widely recognized in routine clinical practice. Because the potential association between SARS-CoV-2 infection and petechiae was not well established, I reviewed and collected relevant scientific literature concerning COVID-19-associated dermatologic, hematologic, and vascular manifestations.
Subsequently, following vaccination with the Pfizer-BioNTech COVID-19 vaccine (BNT162b2/Comirnaty), I developed Stevens-Johnson syndrome (SJS).
