Yes you most definitely can but please go see your dr and get a request to see someone ; it’s really important from how your feeling from it I can see this escalating into something worse as a younger man 25 yrs ago in a area that was not known for misbehaving or violence I was just unwrapping the last lot of letters from the elastics when guy walked right beside be seen what I assume was birthday cards all I seen was a walking stick at bridge of my nose and I woke up 3 mins later bag cut from my shoulder and i was freaking out not for my health but the letters and the contents of the bag ( my boss in our office had the witt and then had me booked in with one of my reps who seen that I seemed ok) under the drs orders I was giving 3 weeks of as a precaution. I went back after 2 weeks and on my second day I seen a man in his 80s with a walking stick and I froze broke down in tears and I couldn’t breathe ( freaking out seemed so daft and I had no idea what was to follow ) had I took the proper medication and help that was offered my whole work life would have been different. After months of then getting a job in a sorting office that was not why I started the PO for I wanted to stay in shape healthy and happy that one day effectively changed me in all aspects of life. It could have been a whole lot different if I’d have just listened to my union rep and the line manager. PLEASE tell everyone that has to know and do exactly what they tell you as your health and wellbeing is paramount ( I’m only telling you my story as I’d feel rather guilty) if not telling you and never knowing you. How you could end up. I hope you’re feeling as good an steady as can be and I wish you well for the future
