A few days ago I injected 1.5cc of test suspension..Yeah the water-based stuff...well that stung like h#ll!!!!..well it has felt like a knot is under my skin since ive injected. I hit (actually someone gave me the shot) my right glute. Its been almost 3 days and its still tender but the knot is the size of a golfball...Any experiences or feedback would be helpful........Thanks
