Hii
It could be mostly a back muscle spasm due to heavy weight lifting as you said.
It should go within few days with medications and exercise and some precautions.
If it doesn't resolves then it could be something else like disc problem or canal stenosis.
For detailed consultation kindly connect with me through practo .
Let me help me out.
Thanks 👍
