Will shaving my legs get any better?

ok, well i've had a history with removing unwated hair on my legs. i started shaving when i was 12 an electric shaver [ i have dark thick brwon hair and i'm light skinned but Hispanic] and i felt spikes and so i also did the razor EVERYDAY because i wanted to be smooth and silky then my legs got bad that red dots were ony my legs and blakc dots too and in eighth grade it got so bad that the next day, you could see the hair on my leg the next day! so towards the end of freshman year, i started waxing, it was good but then since it causes red bumps and when htye went away, it caused scarring. so i asked my Dermatologist [ on yeah, and btw waxing also made me get black dots and when i squeezed the follicle came out!] he said tha ti should start shaving and that it would get better over time? will it? and should i bleach the hair? this has been affecting my life for 4 years now and i need to find a solutin, would be very much appreciated if you helped!!!!!!!!!!!!!! :))))))
