I finished with a 10 day dose of doxycycline 3 days ago. At about the 7th day, I started having nausea, loss of appetite, headache, sore and dry throat, sensation of burning on my skin (especially my arms), severe muscle pain in my upper back shoulders and neck. After I finished with my 10 day dose, the nausea and loss of appetite mostly went away, but I am still having headaches, sore throat, muscle pain and the sensation of burning on my skin. Does anyone know how long these side effects will last?
