Having cold chills and dizzy spells. Injected test into my left thigh on Wednesday, I can barely walk on it or move it. No redness or swelling, happened a few weeks ago also after injecting into thigh rather than buttocks. Took a hot shower this evening then left for shopping. Drank a bottle of water also. Now having pain in the thigh, and when I move my thigh hurts and I get a cold chill throughout my body, almost want to pass out. Not sure if this is flu like or from what I ate for dinner. No throwing up or diarrhea.
