Yes completely normal. You will feel like shit the first few times you take it, stack up on painkillers but your body will get used to it over time. I take it in my stomach and I get itchy red patches that are tender and sore. They can be quite large too but over time you get used to them

Hi agreed this is all normal. My findings (I've injected about 20 times now) is that I have a preference to inject in the stomach- it is less painful and oddly I do not mark or itch there. My thigh is less preferred - I mark there within days and the redness stays for a couple of weeks. I have not tried on the inner arm - just think I would struggle to get the needle in flush -but this will all improve with practice. Recommend you do rotate the sites through as the manuf suggests. Good luck
