I am a 30 year old male. I am suffering from blurred vision. I could not focus properly. Also, I have dizziness and stiffness in the neck, which sometimes continues for the whole day. An MRI brain was done and it was normal. The blood tests including thyroid profile, LFT, KFT, vitamin D and B are also normal. My doctor told me that it could be anxiety. I was under Allopathy treatment for three to four months and homeopathy treatment for four months, but I did not get much benefit. Now, I am not taking any medicine. Please help.
