I took a shot in my right deltoid, and 2 days later, a shot in my left deltoid. I am 8 weeks into my first cycle. The 1st 8 weeks i was injecting into glute muscles. my delts hurt so bad i can't even dream of lifting right now. it's been hard for me to even get a good night sleep, i keep waking up due to delt pain. it's been 4 days since my first delt injection. do pain patches work for this type of problem? how can i prevent this from happening again if i want to continue delt injections?
