I pin 2-3 times a day, stomach only, with no trouble apart from some tiny red dots. Daily I take a peptide blend, plus NAD+ several times weekly, and those can sting slightly but it fades once I'm done. Reading your post, what jumped out was the question of what you are actually injecting plus how many times you poke yourself per day? Irritation that bad seems abnormal. Possible causes of an injection site reaction include skipping thorough alcohol swabbing around each injection, being very sensitive or allergic to what you inject, unsterile peptides, dirty habits like reusing needles (or letting the dog lick the spot, joking), or thirty jabs daily with dull needles. Does any of that fit you? Whatever's going on sounds unusual and miserable, so I hope you calm it down soon!
