hi just looking for some advice, around one month ago I visited my gp and mentioned I had a tender lump which is not quite on armpit just kind of outside of it around the middlebut on outer area if breast, hard to explain doctors said not armpit and not quite breast either. I saw a nurse two weeks later and was told there was no lump and was given a to optics because it is so painful she said burst access or cyst. Obviously antibiotics didn't work so went back to doctor last week and she found the lump straightaway as did the senior gp, it is around 1.5cm and she said it was soft but not a cysts, access, lymph node or infection. So I'm quite worried now it's extremely painful to touch especially during the night it wakes me up and on a morning after waking, not sure whether it's because I'm busy doing things during day but I have been touching it a lot, I have been referred to a breast clinic, I am 26, everything appears normal everywhere else according to nurse that couldn't find the lump during a full breast examination she said it was my rib, I asked the doctor if it was in my rib she said no but it feels like there's either bone or muscle running along into breast and the lump is near the end before the armpit, generally I'm ok i do have a lot of joint aches etc which I saw doctor for the first time but took lot of blood and everything came back normal, I'm aware that cancer is definitely a possibility bug wondering if anyone has had a similar experience, the pain feels like a very bad bruise and sometimes stings, thankyou
