I hardly slept last night...All my joints were aching. I felt my neck aching as well, at first I thought it was stiff neck. But my experienced hands detected a series of post-auricular cervical lymphadenopathies, and I noted soreness in my throat. It can be a systemic infection (on account of the joint pains and I think I detected a slight increase in my temperature). But I hope it's just a simple sore throat. I must have stressed myself out too much with physical exertion in my gardens.
