Sir around 4 months before I was given laryago and voveran intra muscular injection then I developed a black spot around injection site later it started to form a thick scab eventually fallen out due to dress and I found red flesh like depression and applied bandage later again it scabbed and I removed it it became small but inner red fleshy depression now it scabbed again but small. I started to worry its blac around 1inch, pls help me out and guide me please. Thank you so much God be with you.
Black spots can caused my wrong injection technique or it b12 injection you can treat it by hot fomentation this will solve your problem in no time Good Luck
