The fever you speak of can be brought n by any type of test...test flu. Usually, if you do get it, it will subside fairly fast, but if it doesn't, you need to reevaluate things.
The lump is typically brought out by 1 of 3 things. In sust, it can be the prop that's part of the sust. In any UG test, including sust, if it has a high BA content, this can cause a lump. Finally, a bad injection of any AAS can leave a lump.
