I've been cycling for about 4 years, 3 or 4 times a year, so I consider myself seasoned on giving myself injections. Two weeks ago I injected on my right cheek and immediately started coughing for about 5 mins. Following week, left side, no problem. This week, right side, coughing again. My throat feels like I just inhaled a cigar and chest is tight. No bubbles in the tube and I only injected 1.5cc and this is about my 5th week. Anyone know what the hell this is??
