As Laura said I'd get it checked ASAP
Ah beans so I guess it could be serious, I was kinda hoping it’s normal 😅😅
I had to get tested for blood clot and they do it by a simple blood test now! X but i will also say, holding a baby and breastfeeding etc can just hurt your shoulders and back and put pressure on you which can cause postural pain x
I would def talk to your GP! Sounds scary, and what if was a blood clot or something related to being on blood thinners? My aunt has had several blood clots and ends up in hospital to clear up. It’s life threatening, so nothing to mess with or wait on…good luck!
