Absolutely this can happen. Since radiation continues working even after you finish treatments, things still will get a little worse. Usually around 3 weeks after finishing treatments most patients will notice they are beginning to have more good days than bad. Its almost like one day you wake up and are in shock when you really dont feel that bad. Recovery can be full of ups and downs, even after having a few good days a patient can have set backs. It can get pretty discouraging when all the patient wants to to be well again and return to their previous life. It will eventually happen. A complete recovery can take up to a full 2 years. Most of us have felt pretty good after about 6 months and even better at the one year mark.

About your burns. I hope you have some prescription cream like beta-val. If not, ask for it. there are many different ones out there. Take that thick cream and pat it onto your wounds. If the wounds are 'weepy' place a non stick gauze square on there and let the cream soak in. Never rub it in as your skin is much too sensitive right now. Apply the cream several times per day and avoid letting the shower run on the burns. If it helps, my wounds were very bad open oozing sores but after they healed I had no marks at all.
