Leesa

I went and got shot on my birthday which was on Wednesday November 8th and I noticed about 1 day after I started getting chills fever headaches back to back and then the huge bruise on my back and a huge lump that has gone on now for 2 weeks I took ibuprofen and an antibiotic thinking that it will go away and it never did and now I'm concerned and wondering if this is normal because it is painful
