Hi dr Riad Alalaili,My name is Laila. I underwent a thyroidectomy during 2015 as I was suffering from a very small tumor less than 1 centimeter 0.7 in size and it was trapped inside the thyroid and it was a papillary tumor and so far I do not know why the parathyroid gland was removed, as you told me that my condition is very easy and all that I need it is a gland excision only, and I will suffice with a pill after the surgery that is only thyroxine, and since the procedure I suffer from permanent pain due to a lack of calcium, I suffer from distraction, lack of attention, less of memory ,permanent pain in the bones, numbness in the body, and rapid heart rate because I take every day 5 pills of calcium 600 And vitamin D which caused Me stomach ulcers, I need help and treatment How can you help me , You did the surgery mistake for me with all my respect you need to take some responsibilities when I came back to America all the doctors I get treatment with from Told me that any surgeon with experience will never do this mistake .
