My lower back has been absolutely killing me today. Does anyone know of any remedies I could try to address it? I’m trying an ice pack and fixing my sitting posture right now, will be sleeping on my side to relieve pressure on it tonight, but is there anything else I could attempt?
Honeslty - see a doctor.
The advice peole are offering here will either help or do nothing or make your problem worse and if you try all of them - chances are pretty high you’ll stumble across one that will make it worse.
Your pain is a symptom, not a problem. You need to find out what the problem is before you can fix it.
