And today I just went and get my last shot. So I found out that the girl in the office had the same side effect but she had it of her second dose (hence split made). So, they just told me to call and report it. So it could be like a side effect I guess because I did not know that, there nobody else had, he said she had, she has it so many times (further clarification unknown), she went in and done X-Rays and stuff and they could not find that. So I am thinking this probably, she got the same shot that I got, so I am feeling this problem from the same thing.
