[|Human|] Some rashes have come upon my legs below the knees from the past 1 month. but no pain or itching.just discolouration, something like patches. i was asked to do blood test.  I am 57, female.my Hb was 12, ESr 25. My Dr advised Alegra 120 mg- 1per day for 10 days.is that ok. he told ESR 20 is good, 25 is also not dangerous. what can be the reason.
[|AI|]  Howell come to ChatDoctorIf the skin lesion does not cause any symptoms then systemic disease need to be ruled out, blood sugar level need to be tested, some time skin biopsy could help in diagnosis, ESR is questionable here, in my opinion better to have dermatology opinion because clinical observation is the best way of diagnosis when it is question of skin disease, hope this information helps, take care.
