Hello Welcome to health care magic Deap patient, skin manifestations of liver dysfunction or liver disease include jaundice, itching, scratch marks due to itching, shiney thin skin , hair loss, pedal edema, palmer erythema, telengiectasia/spider nivea which are dilated arterioles in a star like branching pattern. your red itchy bumps in skin over trunk and limbs does not seem to represent any of these but still the doctor who had seen the lessions is the best judge to tell wheather liver clearence is needed or not and there goes nothing wrong in getting it done. I feel that these red itchy bumps in skin may be due to allergic reaction to the medicine that you might have taken, or the moisturiser that you are applying or due to insect bite like mosquito bite , scabies or some other dermatological problem , so you should also get a dermatological consultation done wish you speedy recovery thanks D r Arshad
