Ld flap reconstruction backpain

Hi,

I had a LD flap reconstruction mastectomy done last Feb and in the last two months finished with Herceptine but am still on Tamoxifen.

I have the most awful backpains and chest pains, I am hoping it is the nerves healing I guess, but it can completely wind you as if you have been stabbed?

Is this normal to still have this a year on?

I have asked my doctors and they have done scans but not found anything and have quickly dismissed it as nothing, but obviously I am still extremely paranoid.

 If anyone could put my minda at ease that this is ufortunately normal I would be very grateful.

Thanks

I had Ld flap left side 2004, right side 2005.  Today, I have achy sore muscle across my back where my bra strap is.  It is not all the time I guess it is when I am tired..  Otherwise no complaints.
