Can I use any laser treatments after being diagnosed with presumed Polymorphic light eruption? (photos)

In April I have started laser hair removal on legs and bikini. In late June I have been put on Trimethoprim and after 2 weeks on it got a rash on my back body. Ive been diagnosed with PLE. Since then I was avoiding sun at all and it has faded but not totally. What can I do with the rash and can I continue on laser hair removal? Steroid thickened hair on my tights so I'd like to finish it as well because I have Pcos and excessive hair. I'd like to use laser for acne too.
