Female, 21 Years Of Age. Have Struggled With Reoccurring Small/medium

Female, 21 years of age. Have struggled with reoccurring small/medium patches of shingles starting around the age of 18. I get such small patches that last a couple days or a week at most then they go away and they barely hurt so since I get them so frequently I stopped going to the doctor every time because it costs a lot to get medicine for them when they just keep coming back anyways. I’m not old enough to get the vaccine though? These are annoying.
