I read it and have been following it. I have had the same problem 7-10 days of swelling until I started heating, massaging and S-T-R-E-C-H-I-N-G. That is what got the shit out of there. I used a 5/8 in my ass obviously wasn't deep enough. That is why they say go as deep into the muscle as possible. And don't message the area until the next day. Massaging it after injection will cause the fluid to come up to the sub-q area and will not flow well or dissapate. However sometimes the stuff will just not go away until heat, streching and massage forces it out. I was worried also because I started sweeting at night when I was sleeping. The redness could be caused by any number of things - heat, massage, blood flow from swelling etc.
