I am on a cycle of sus 500 and have had a real problem with getting sore at the injection site. I injected my right glute this Monday and it is now wednesday and the soreness has spread a little across my glute to my lower back and feels just a tad puffy. No redness, no fever, headaches etc. Just slightly puffy on lower back and harder than normal on glute. Is this something to be concerned about or is it possible that the oil just spread a little and irritated other tissue? this was my fourth injection.
