This is Benedict I am new here. Does hiv cause lips discoloration and cause them to turn red. I have been developing lip discoloration and also experienced hair changes from normal to brittle hair. I have also suddenly developed lactose intolerance. Last year I went to do an hiv test 4 times and it came out negative. This year I have gone there twice and results are still the same. Is there any other disease that might have symptoms similar to those of hiv cause I have gone to the hospital and the doctor says everything is normal.
