Hi Amelia,
Welcome to the forum.
Plaquenil can take some time to kick in. In my case it took 6 months before I started to see any improvement. Hopefully it will be sooner for you.
Scarves are great, but if you are going to be out in the sun you might want to consider something with a wide brim. The sun can trigger flares for some of us. It doesn't hurt to take extra precautions. A good sunscreen is a must too.
Take care,
