My 70 year old mother fell and hit her head very badly about 2 weeks ago. They CAT scanned her and said she looked okay, She had increasingly bad headaches over the next few days, getting to the point of vomitting. We took her to the emergency room a second time. They performed tests and ended up giving her pain medications . The last couple of days she has been sweating near constantly and profusely. She looks like she just worked out, covered with dripping sweat. Does she need to return to the energency room? Or can she wait until her doctor returns in 3 days?.
