### input:
Hello, I am a 43 year old woman who had emergency surgery (caudai equina L5S1) six years ago and subsequent disc degeneration leading to further herniations of varying severity from L3-L4 through S1-S2. I was left with almost complete sensory loss in all areas innervated by L5-S1 and now am loosing sensation in other areas (primarily at the levels of L4 and S1-S2). I have cervical degeneration as well and compression at C2-C3 C4-C5 but C6-C7 shows central stenosis causing muscle weekness, sensory loss extreme pain etc. I have a neurostimulaor, morphine pump, oral meds etc. Is there any known link between petechiae in the lower extremities in areas where there is prolonged sensory loss? My feet and lower legs (both) are covered in petechiae. If I put my leg under my rear and apply pressure i.e. my body weight I get a cluster or red resembling a bruise that lasts for weeks despite only having applied moments of pressure. thank you for your time.

HelloI may suggest having serum prothrombin time (PT), bleeding time clotting time and platelets counts done for any abnormality there which could point to some other reasons or pathologies. Petichae in sensory loss areas may not be due to nerve sensation deficit, yes long duration sensory loss does make skin vulnerable to bruises and may make it brittle and easy petechial formation may occur secondarily. It is best if sensory loss is suspected as a cause, to massage skin daily with Clemens oil and limb exercises for improving or maintaining vascularity and skin tone to prevent bruising. Take multivitamins, calcium and vitamin D supplements, vitamin A etc. You may consult a physician for your symptoms. Physical therapy is the mainstay for lumbosacral issues, for cervical reasons too, using collar and isometric cervical exercises, unless your surgeon decides for discectomy and fusion surgery best wishes
