In brief: Complicated

Some of the pain is a result of the inflammation induce by the infection through the release of cytokines (chemicals released by cells which influence the behavior of other cells).
Some pain may also be a result of the death of muscle cells by apoptosis induced by invasion of the virus. There may also be microhemorrhages into tissues creating pain.
