i had my blood pressure done on my bad side!! i totally forgot
what will happen lol? will i be ok?

I’m sure it will be fine. I was in isolation for a week due to a severe chemo burn to my hand and no immunity over 3 years ago. There was no alternative but to use my bad arm for blood tests every day. I also had to have Herceptin done on that side and I haven’t had any problems so far, touch wood.

I agree with what Cherub says - don’t worry. I know that in an ideal world you want not want that arm to be used, but that is not always possible. I had to have chemotherapy administered into my “wrong” arm twice because they just couldn’t get a vein in the right one, and I have also like you forgotten once and had my blood pressure taken on the wrong side.
