I've had this happen to me multiple times, I will do a successful injection and everything will be fine. Around three days later, the area where I injected will get red and swollen and be warm to the touch, also very sensitive.
I know it sounds like infection right. Well this has happened to me about 4 times since I started pinning EOD 4 weeks ago.
Most injections I will get pain for a few days and it's gone. But every once in a while on that third day the injection site will flare up and get red, sore, and warm. First time it happened in my glute I freaked out, but the next day (4th day) it was gone.
Same with first time I pinned right delt, 3rd day it flared up, next day it was gone pain and all.
This evening after lifting I noticed my left delt is flared up, tender, and red. Of course I pinned it 3 days ago. I'm not freaking out due to past experience, I'm about 80% sure it will be gone tomorrow. But what gives, why does this happen?
I'm running Prop 150mg/ml EOD btw for 8 weeks btw. First cycle.
