Hy Dr. my son was born on 10/6/21, at birth time his left hand fingers tips are showing pinkish red color, but after 4 days fingers tips color change into black. We consult the ped. Doctor & done all necessary reports like CBC, 2D echo, S.billi, PT, APTT, thyroid, CRP, USG with local part with Doppler left hand etc. but all reports are normal. Even doctors are not clearly find the reason of fingers black spot. I don’t know what to do? Plz give ur valuable feedback. I’m waiting for your kindly response. Thank you
