Two hard lumps on both sides of the waist may be caused by normal bone tissue, lipoma, fibroma and so on.
1. Normal bone tissue: if the hard lumps on both sides of the waist are symmetrical, of the same size and asymptomatic, they may be normal iliac bones. The bones raised on both sides of the waist are called iliac crests, and the bumps at their front ends are called anterior superior iliac crests.
2. Lipoma: it belongs to benign tumor, it is a kind of slow-growing adipose tissue, which can be moved by pressing hard, most of the lipomas will not have pain, and if there is no symptom, it usually does not need to be treated, and if there is a symptom of compression by the surrounding tissues, it should be surgically resected.
3. Fibroma: mainly seen in the connective tissue within the muscle and its covered fascia or tendon membrane, most of the fibromas are benign, but a few are malignant, surgical excision is the first choice of treatment for fibromas.
Two hard lumps on both sides of the waist may also be other reasons, patients can go to the hospital for consultation, to clarify the nature of the hard lumps, and take corresponding treatment measures.
