Hi,
I'm 22 years old.I am actually a tall guy so I try to sit straight most of the time.But for few days I couldn't sit straight even for 30 minutes and I am getting upper back pain and tingling sensations in upper back which is disturbing my study focus a lot.Please I don't know which deficiency or what happened but I am getting these pains even when I sit straight.I don't have any injuries before.I think this is some
vitamin/mineral deficiency.Because of this I am always sitting in a crouched position on bed.Please help me 🙏
