Right leg pain and back pain. Me sir!

Sir, I have been facing this problem since 1 year. I consulted neuro physician and orthopedic too.physician suggested me Bio d3 max, sanvicobal, myospas. I got releif from pain after a month. But the pain kept attacking 6-7 times during the year. I haven't visited doctor but I used the same medicine earlier prescribed by the physician. But the pain again encountered to me during this pandemic. I couldn't even move my leg a bit. I live in a small town. Due to this lockdown , there are no neurosurgeons coming to our place. And I could not even go to city due to lockdown. From last night Iam also facing back pain. Sir, what would have been the  actual reason for this. Will it get cured for medicines or is there any surgery Iam really very much worried. Please reply me sir
