Thanks for your question on Healthcare Magic.
I can understand your concern.
I don't think it is
Scoliosis.
Scoliosis is related to spine, not
sternum.
Scoliosis is sideways protrusion of spine. So I don't think your lump near sternum is due to Scoliosis.
In my opinion, you are mostly having
costochondritis. It is inflammation of costal
cartilage and it can cause swelling.
So follow these steps for better symptomatic relief in costochondritis.
1. Avoid movements causing pain. Avoid bad postures in sleep.
2. Avoid heavyweight lifting and strenuous exercise.
3. Take anti inflammatory and painkiller drugs.
4. Apply warm water pad on affected areas.
You will mostly improve with all these in 1-2 weeks. If still not improving then get done
ultrasound examination of local part and CT scan to identify the cause of swelling.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
