It gave her a problem like she could not reach, it hurt when tried to reach things. About 2 or 3 weeks after the second dose both of her arms felt the same way, under the arms muscles when driving it hurt her under both of her arms. It was ongoing, it was terrible, and it got worse. She started documenting it. About 3 weeks ago, when she sat down, she could not get up, underneath her backside and the thigh muscles hurt. It was ongoing and everything seems to be getting worse. Reaching was terrible, she was not sleeping. She was having a terrible, terrible pain under her arm when she asleep and she went from bed to couch. She read that it might help to try to use a pillow when trying to get up. Stated that, the only way she could get up from bed was if she leans on a pillow. In the morning it was the worse and she could not get out of bed, like she did not have the strength to get out of bed. She was then walking, and she walked through it, her behind, it hurt.

What was crazy is that her arm pain was only for a short time prior and that was weeks before. She did not realize the pain was gravitating that it was moving. Hoping we can come up with a cure, did not want it to go on forever, it was scary. She was vey tiny. She had high cabinets and she was used to climbing 6-foot ladders to put things away and now cannot reach it.
