Some time ago, I mentioned here on the blog that I was severely struggling with back pain. Oddly enough, the pain came back when the global lockdown began. I rationally thought that the problem was probably linked to my mattress, but then my grandad disclosed that he too was having the same kind of pain, which really feels like a needle going through the skin and right to the kidney’s area. He was the one pointing out to me, however, that his pain was caused by the fact that both knees were pressuring ahd hurting each other during sleep. Could that be my problem too?
