I have what seems to be a swollen Thyroid Gland. The pain is constant on my thyroid and goes up the left side of my neck, it also sometimes affects my right arm and shoulder to the point that its pretty uncomfortable. :( the pain right now is in my neck (thyroid) area, by my collar bone by my neck and down my right arm. Late it will switch to the left side of my neck and shoulder and arm. I also have a very high heart beat constantly. 130 to 132 BPM . I have joint pain in my knees at times, my period has shortended. I will go for two or three days then stop completely than what would be my last day I may spot just a small amount then it's done. I also get very hot. While others are wearing a jacket I walk around with short sleeve shirts and flip flops. I sweat and am so hot all the time. I'm guessing this is due to my heart pounding non stop. Also and I'm not sure if this has anything to do with my thyroid or not but it also happened when I notice all these other things happened. When I wake up I can't hardly walk. The Back of my calves behind my knee hurts and I feel like my feet are locked up. From my ankles to my heals, everything is what I would describe as frozen. Both legs feel the same. I have to walk it out in pain until its gone. I feel like a old lady :(. Something is wrong. I'm guessing tyroid since the area my thyroid is at hurts so bad. I also have noticed a problem swallowing my food. Again any info to help me along this journey will help a lot. Thanks again.
