Reactive Glutes

I have been on a cycle of test prop and equipose for athree weeks and I have followed the injection procedures as per the text book.However I seem to have grown two huge lumps on each glute which seems to happen the next day after a shot. I find it extremely difficult to lie down or sit down and I am not sure what is going on. I have taken some NSAIDS to reduce the inflammation which temporarily seems to help especiall with the pain. Does the the collective wisdom of the community have any insights into this one?
