Please don't apologise. Anyone is welcome here, even though no one wants to be here. I'm not much help I'm afraid but my answer will bump this post up and you may get someone who knows a bit more.
All I will say is that if you're worried it would be better to get it checked out. Did you have a BC nurse during treatment who you could get back in touch with? Or could you ring oncology?
I sincerely hope everything is ok xxx
I hope you will soon have some replies to your post from fellow members.
