Sausage shaped lump on left side lower abdomen

Hello, I have a long sausage shaped lump which feels hard, going from my hip bone and down curved towards my pubic area on my left side.  I have no other symptoms and feel well, and was just wondering, after a lot of google searches, if it could be sigmoid colon? I was wondering if it is even possible for people to be able to physically feel it? If it’s full or if i haven’t had any BM? Wondering if people have the same problem? Thank you :)
