I can’t orgasm without pain

I’m 24F, I’ve never had a problem with masterbating or reaching climax, but this last sort of week I cannot seem to get there, I will do my normal stuff and it’ll feel good, and then it’ll get overly sensitive and painful in my cliteral area and I can’t continue, I try again a few minutes later but the same thing happens, I’m still built up and frustrated but I can’t actually orgasm! I have no idea what is going on. I haven’t had sex since January, but never had this issue with doing it myself
