Hi Doctor, I am having issues with my legs sometimes swelling and this would not happen when I m home but when i come from outside like work or outing it swells little bit. I got thoroid test done it was normal and i had low heamoglobin so i m on medication. I thought because of less haemoglobin my legs don't get enough blood circulation and they swell sometimes. I may be wrong. What do you think it could be? I have been taking tablets for haemoglobin and vitamins D, B12 and B13 which is low in me. What shall I do to avoid swellings? Thanks!
