I have been injecting Test. Enanthate for 5 weeks now, 500MG/week (2cc) in my glute. Just this past week a lump has developed under the skin in the spot I have been injecting. It's hard and about the size of a quarter. You can't really see it by looking at it (but then again I can't get a very good view of it myself) and it does not hurt, however, for a few days after my last injection (which is the one it showed up after) I did have more pain than usual for a few days. I have since injected again (in a different spot) and there is no pain at all. Just wondering if anyone had an idea as to what this might be, and if I should go see a doctor about it.
