Headaches started a couple of days after the first dose probably started the next day and started coming and going. This stopped prior to the second dose probably a week or week in a half maybe two weeks before getting second dose. The headache only lasted about half a day, it wasn't that bad. She recovered completely. Arm sore, red only happened with the first dose as her arm did not hurt at all after the second. This started the next day or even the same day but she kept it comfortable and probably stopped within the first week and it did not come back either. She has recovered completely. Sharp pain through arm go and come. This started after the first dose so in that week or week in a half area and it stopped about at least a week before the second dose somewhere in that period of time. She has recovered completely. Hallucination: she was laying down at night and something would come across her head that she was not thinking. It started right after the first dose probably first, second, or third night but it stopped like all the rest of it in same period of time.
