I noticed my leg was hurting and I could feel a knot had formed. Also when I kneeled down my leg always hurt. I read where oil could build up at injection site so I started to pull it out. I honestly pulled out about 13cc's of oil. Is this common? Why did my body reject the oil and not absorb it? What was I doing wrong? I am sure it was not an infection as I smelled it and felt the texture and it was pure oil.
