There is something you can do until a real farrier gets there.
Pick out the feet and clean them really really well. You can use the hoof pick and scrape away chalky sole and dirt on the sole and use the hoof pick brush to scrub out the frog and commissures. I put dawn dish soap and water in a spray bottle (just make soapy water) and use my hoof pick brush to scrub the feet. I just spray and scrub and spray and scrub till the foot is actually clean and the water runs clear. No need to rinse the soap off. It will help if there is thrush. If the frog is painful when you scrub, you have found the problem. Clean every nook and cranny well but be careful. I sometime use Q tips to really probe out gooey holes and get them clean.
