<s>[INST] Hi I had a meningioma removed from my brain  that was pushing up against my optic nerve 2 years ago. I have had two  MRIs since my surgery, and everything looks great. The problem is right after my surgery I was recovering just fine and some time possibly 4-6 weeks after surgery I must have lost my sense of smell. I could definitely smell after surgery!  I can taste,but cant smell. I sometimes have phantom smells. Do you think this may be part of the slow healing process? Should I try acupuncture? [/INST] Hello I have gone through history provided by you. Good, surgery for meningioma was successful. Change in smell or its loss is due to damage to olfactory nerve which lies in vicinity. This could be prior to surgery or can be during surgical process. It is inevitable consequence of surgery. You should learn to live with this minor deficit. There is no specific treatment. Trial of acupuncture can be taken and hope for good results Regards Protein </s>
