Hi I woke up this morning with a sore throat, ear ache, achey muscles and I also feel panicky when I breathe. What could it be or caused by thanks?

Viral infection. The complaints are typical of an upper respiratory viral infection. The panic is your anxiety to the fact that you are not feeling well. At age 18, with a normal immune system, you should recover with 10 to 14 days. If the symptoms get worse or last longer than 3 weeks, see your physician. Treatment is supportive such as liquids, Vit C, rest, time and do not worry.
