<s>[INST] HiI havent felt myself in months I get many different feelings during the week to dizziness, head feels blocked also numbness and tingling in fingers at times and a cooling feeling that goes through my body my family thinks Im crazy. Should I be concerned. I had an MRI a year ago and all was ok but I only had migraines then. [/INST] Hello! Thank you for asking on Chat Doctor! In my opinion, your symptoms are not indicative of any serious medical disorder. Anxiety or a metabolic disorder can trigger all this clinical situation. For this reason, I would recommend performing some blood lab tests: - complete blood count for anemia-thyroid hormone levels for thyroid gland dysfunction- blood electrolytes- vitamin D levels for possible deficiency. Hope you will find this answer helpful! Kind regards,  </s>
