I have a large gray tabby that I rescued and got fixed and he started limping on his front leg. I took him to the vet....he examined him and said that he dint feel any breaks. Gave him a shot of steroids and he said he should be better ....but hes not. Now he is hissing and trying to run and hide. And now his leg is swollen ......his paw and a little up from there...I believe he is in pain.....I need to take him back to the vet.....anyone have any ideas of what it might be...I feel so sorry for him
