OH and I had the 5th jab (Moderna) on 8 September - local walk-in centre with no appointment made. Neither of us had more than a slight ache in the area of injection for a short time.
I had a more terrible time when I had to have blood taken last week. Nurse tried my right forearm "oops, I think I've gone through the vein", so tried the left forearm. I had two rather large bruises for quite some days, despite the use of arnica gel.
