My wife has experienced different, and has been struggling since the week before Christmas and is still today.
She had a mark/infected spot on her neck and pains all down her left side Shoulder/Arms/hands, she has been worried about it and contacted her GP but couldn't get no contact, anyway she went private to a dermatologist and its Carcenoma first stage skin cancer. To get this removed she needs a referral letter from her GP for which she's had nothing at all back from them since she got told in January.
Just to add i don't have any anti lockdown agenda i just have concerns that lockdown is solving one problem but creating many more.
