I just started with Jintropin, two days. Had the same side effects both days and want to know if it is common. I felt tremendous pressure in my head, especially behind my eyes and tightness in my chest. I actually felt weak in my limbs and a little dizzy at times. I checked my blood pressure and it was normal. Being diabetic and not wanting any problems with pressure in my eyes, I don't want to go any further. I only took 1 iu. Could it be I just took too much?
