Since you had a cold recently, so the possibility of these bumps due to swollen lymph nodes is high. Lymph nodes are small (1-2cm) and bean-shaped nodes. They are very important to your body keeping you healthy. Lymphadenopathy (swollen lymph nodes) is usually caused by a viral or bacterial infection. Other causes include allergic reactions, arthritis, cancer, metabolic diseases, and an overactive thyroid (hyperthyroidism).
Apply warm compresses and these should go away in a few days. If they persist then please get them evaluated for being cysts or the other causes of lymphadenopathy. FNAC of the lymph nodes may be required. I hope it helps. Take care and please do keep me posted on how you are doing. Kind regards.
