I'm on week 9 of MJ, currently on 5mg and has been going well with very minimal side effects. However past 2 weeks I've had itchy red spots/hives at the back of my neck. This week I've had a 3-4 spots pop up in random places on my body. Not at injection site.
I've not used any new cosmetics, soap etc so can only be linked to MJ. But would an allergic reaction not happen after my first dose? Would it take 8-9 weeks?
