Thank you, Ginny, Jane, and Singdaw for your concern.
I called Nurseline and spoke to an RN about my incident today. I don't think it warrants an ER visit, but I thought it best to talk to someone knowledgable. I don't have any of the warning signs except a sore head, but she asked me to have a friend call and check on me. I've arranged that and tomorrow I'll call my PCP. I already had an appointment scheduled with him for this Wednesday, but if I'm worse I'll try to see him tomorrow. I woke up this morning at 4:30 and couldn't go back to sleep, so I was feelling somewhat out of it to start with. I shall rest and make use of a pack of frozen peas.
