Hi got a little bump on my hand while playing with my dog and no blood or anything so I went to doctor took tetanus injection and first dose (of 3 doses) i.e on 20 may but when I visited doctor 2nd time and I told him that there was no blood after bite he said there is no need for injection so I did not take 2nd and 3rd dose but yesterday I noticed that at one side of my shoulder where I took a injection there is little bump and has swollen minutely (may be it was there earlier but I noticed it now) and not on other shoulder so I this has to do anything with rabbis? Also our dog is 4 months and is given 2 injections out of three and as I said I had no blood but only a little bump so is there any cause to worry? My dosses were scheduled on 20,23 & 27. maybe I took only 20 may dose i.e 1st one?
