<s>[INST] I bent down to pick up my daughter and had immediate pain in low back, hot sensation up back, sick to stomach, loss of vision for about 10 minutes, bad headache, legs weak, and tingling in face, top of head, back of head.  I did this a week ago and still experience tingling in head and face.  My iron was 9.1 and blood test came back normal. [/INST] Hello, I have studied your case. There is possibility of transient ischemic episode leading to pain in your back and loss of vision temporary.  You may need clinical examination to confirm neurological weakness, BP and other vital parameters. Another probability is due to compression of this nerve root there is pain in your back.You may require MRI brain and spine.For these symptoms analgesic and neurotropic medication can be started.Till time, avoid lifting weights, you can consult physiotherapist for help.Hope this answers your query.
