I have been experiencing pain in my mid back - radiates to my right side. I thought it was like lower back pain, which I have had for many years, but this pain is sharper. I get some relief from icing, but I get up & it returns. also thought it was related to my job, office work-sitting 8 hrs a day because I had something similar, a couple years ago. stretching, swimming did bring relief at that time. going on daily for over 1 month. started swimming again in june, saw my DR. & he suggested to not swim for 1 week, but still no relief. i am 5 2 & weigh 225, have also been dieting 4 wks also & lost 15 pounds - balanced protein, carb & fats. I sleep well, no pain at all when I am laying down.
Hello, I have studied your case. Most probable reason for your symptoms could be postural problem as you may be sitting for long time and obesity. I will advise you to do MRI spine to see for any disc bulge or spinal canal stenosis. And also check your it B12 and it D3 level. Medication like methylcobalamine and analgesic will reduce pain. You can continue yoga exercises and focus on spine extension exercises. Some exercises which can be done include-Spine extension exercises, Lying on your stomach flat lift leg 6 inches from ground, do it for other leg. Now lift both hand and leg simultaneously, 6 inches off the ground and supposition for around 10 breathes. Core stabilizing spine exercises will help. You may consult physiotherapist for guidance. He may start TENS, or ultrasound which is helpful in your case. If not relieved you can take epidural injection. You can cure disease by doing all modalities with balancing your posture habits. Hope this helps. Wish you a speedy recovery.  If you find this answer helpful do not hesitate to rate this answer at end of discussion. Take care
