Τι σημαίνουν οι μικρές αλλοιώσεις εξωκυττάριου λιπους σε μαγνητική οσφυϊκής μοίρας;

When I changed home and started sleeping on a softer mattress a couple of months ago, my right leg started getting numb. I have had lower back issues for a long time, so I thought it was related and didn't pay much attention. Now, there is a slight but constant loss of sensation and pain, along with tickling and itching. I'm worried about being too late so can you please help me, how serious this might be, and which doctor should I see?

Hi I have a sharp pain in the tip of my right shoulder which happens only when I am sleeping. Only if i sleep on the other side it goes away. When I turn again on my right side it is a sharp pain like a knife. During the day my shoulder is more than fine, and I can move it normally.
