i dont walk at all as doc sd bed rest i just walk in home and i am taking calcium iron vitamin b and d3 tablets i have thyroid but its control

This appears to be a B12 and D3 deficiency. Please discuss the same with the doctor. You may be advised certain tests which will confirm the same and then the doctor can start supplements. These are just vitamins and minerals and hence completely safe

I feel you got back pain too earlier. And why joint pain? how much kms you're walking daily. Hope your gynac has already given calcium tablets. Try drinking milk daily. And before going to bed, have bath in hot water. Pour hot water on the sore areas. You can even use hot water bag for relaxing. Have enough rest. TC
