I went to my ob yesterday and she told me what I already knew to be true. I started my Valtrex.. I am hurting soooo bad

it's not only the open sores burning along with the one on my urethra that KILLs me everytime I pee, my legs hurt so bad!! I had symptoms a week before I saw any sores. I thought it was just a UTI..anyways, I was reading on here to watch your dirty laundry. I live with my sweet grandmother and she does my laundry even if I tell her not to. I would hate for her to contract this through my laundry! Please tell me this is highly unlikely because I don't want to have to worry about her too! I am ready for these symptoms to go away!! It's been 2 weeks
