My left arm has been sore since I came home from hospital - it can be like a dull ache or really sharp pain when I move my arm a certain way - I asked my Dr at my 6 week check up (thinking it was something to do with the drip I had in my arm) & he said it should go away. It is still here & so I thought it was from reaching out of bed to rock the bassinet & also when I carry her I tap her bum with that hand to get her to sleep. I have made a conscious effort to not use my left arm but the pain is still there. I will ask the Dr again when I take Eliana for her 4month shots on Wednesday.
