Hi, welcome to our site. I am Dr Saumya Mittal, MD. Read your query. That is a very significant question and i appreciate your problem. I will try my best to answer your query Feeling cold- The first possibility I would think of in this case is thyroid disorder. You have already said that you have hypothyroidism. I know that you have said that the blood works are now normal, which I am assuming includes thy roid profile too. But there is no harm in checking the thyroid levels again. I would also suggest checking up your sugars and Vitmain D levels. Increase your levels of activity, unless restriced for some purpose. These are simply the commonest possible causes of your symptoms. The list is by far not exhausted. But that will need more detailed history taking and examination I hope this helps you. Inform the reports mentioned above/if any other so I can be of help further. Best of luck. I have given you the answer to the maximum considering the information provided. The results of the tests could further enhance my answer to you. Please do understand that some details could be extracted from a detailed history and examination. Please feel free to ask another query. I would be glad to help you. Looking forward to your return query with the details asked so that I can help you further.
