ok so im on my first cycle of test and after the first weeks shot everything was great.just thursday it was time for the second.after doing it everything felt fine.i woke up on friday and was still ok til midday.but later that night up until now my leg is so sore i cant even walk.its extremely painful.i know the shot was shot in the correct spot of my leg with proper precautions taken so what could be the problem.has this ever happened to anyone and should i be worried or let it run its course.thanks
