What Causes Cluster Of Boils On The Chest With Swelling In The Arm?

Question: Swollen right arm ; huge carbuncle on right upper chest; left arm thinner than right; some eyes of carbuncle have drained . Carbuncle is reducing in size . Should surgery be performed to remove carbuncle or just do antibiotics or remove the push one by one .? The heads are out after I applied a lot of Povofine -Iodine on the lump. Some heads are big some are Small . Done heads have drained, some have not . Some heads have pus but not yet draining. Others have no pus yet showing .
Right arm is slightly painful when not elevated. I do a lot of heavy household tasks. I can lift my right arm .Right clavicle and right shoulders are slightly swollen and itchy . Areas of My right armpit were bitten by ants and spider and swollen , itchy and hard but not painful unless It rubs against my clothes if my clothes are tight. It itches when my environment is very hot or if I wears too much tight clothes . If I touch it, it becomes bigger. How should I treat swollen armpit? If I leave it alone it is not swollen unless I touch it.
My stomach growls frequently but disappears when I eat , comes back after eating nor when I am stressed. I take 2000 mgs of Vit C, Super B Complex and Super B complex Stress . They helped in reducing size of carbuncle and gives me energy. What other foods and Vitamins do I need? Please answer my above stated issues . Thank you. XXXXXXX
