Did 3rd dose of test cyp 300 today. Went smooth. I had severe pain on my first and second pin. 1st one has recovered. 2nd has a red swollen knot on glute. Its bn 4 days and has not let up. I can barely sit down. Is it normal to b swollen and red??? I know pip is normal but i was thinking maybe infected?? Idk any feedback?? Mind u this is 1st cycle ever.
