My wife went through a surgery and anesthesia was tried through spine but she hesitated and they had to take the injection out and give an injection on her hand. It's been 3 days and now she complaints about severe headache and pain in the neck which she can't bare. Doc suggested to take a lot fluids and bed rest. We are going on a long trip in 5 days and not sure if she will be ok by then. Any suggestions than rest and fluids, which can cure the problem early.
