re help me inject the best way of self injection is to use the right size needle and choose the correct spot for streptomycin usually given intra muscularly use a thin needle guage and select a spot on the upper outer thigh no major nerves or blood vessels there clean the area with antiseptic before injection and after make sure to inject deeply a different kind of pain is felt when the needle enters the muscle contrasted to the prick when it pierces the skin ps try to go to a doctor self treatment and self injection should be avoided as far as possible
