So much pain

I’ve got arthritis in my shoulder blades and usually take diazepam 5mg codeine 30mg naproxen. But I’m 7dpo and so so scared to take anything incase it interferes with implantation process if I’m lucky. But it’s killing me, it’s starting to hurt to breathe now aswell! Doctors know about this hence why the medication, I’ve used voltarol gel and paracetamol but that hasn’t touched its. Is there anything you could recommend I can take. I’ve got a 2 1/2 year old son so I can’t be in pain 😭
