<s>[INST] Hi I had an operation on my left side of the head in 2012 because I had a lump that was so painful now after the op I always have these pains especialy when Im stressed my whole left side will pain so badly plus I need to know can I be pregnant since I have these pains in my breasts not on the nipples but on the side of the boobs? Ive had my periods last month but Im stressed now [/INST] Hi, Head surgery has little to do with being pregnant If your periods are regular and don't have any problem regarding the flow then you can definitely conceive. As you have mentioned that you have pain around your breast, thoroughly do a self-examination of them by lightly but firmly palpating on all sides of breast to see if there is any lump (normal breasts should feel soft on palpation). If yes then you need to visit a gynecologist or a physician for a check-up. Regarding your pain on the whole left side of the body, since you haven't mentioned any of your reports I would suggest visiting the doctor who did the operation as a follow-up procedure. Hope you find this helpful. Let me know if I can assist you further. </s>
