My backs been hurting so i was rubbing my lower back and found a lump on my right side right above my hip bone what could it be?

Hip/back lump: It could be many things, but if it is posteriorly located above the sacro-iliac joint, it is typically a benign lipoma. If there is skin retraction, pain, or other findings, check with your pcp or orthopedic surgeon.

Lipoma most likely : Most likely a lipoma, the most common benign soft tissue tumor. If no symptoms and not changing, can be left alone. In extremely rare instances can they undergo a malignant transformation and family history usually helps determine that. The psis (bony prominence near where the hip attaches to the back) can be felt in that region.

Simple vs serious: Our bodies always have things that grow and change. Skin, fat, muscle, lymph nodes, bones, can change shape, get larger, more prominent due to many factors. The vast majority are not cancer but simply unusual growths like fatty tumors, cysts, skin tags, moles, etc. Most cause no symptoms and can be watched. If they cause symptoms or change colors, bleed, bruise or hurt, then see your doctor.
