My husband, 68 yrs old, myself 64 yrs old and our son 32 yrs old have had sore muscles and joints through legs, hips, buttocks , arms, shoulders, neck and ribs, back area for 3-4 days and seems to be getting worse, we are somewhat lethargic and have had sudden headache that does not last long, and scratchy throat , feel like we are getting the flu , but do not really give into actual sickness or any fever. Any ideas? We are the Baxter family, at YYYY@YYYY .
