Hi, Thanks for using Healthcaremagic, You are having High blood pressure and treated for it with antihypertensive medicines if your blood pressure reading are fluctuating take medicines at regular interval and regularly. If you dose is recently increased it may take some time to have smooth control of blood pressure. Recently you also started Thyroxine supplementation please continue to take it regularly. Your burning sensation possibility of some allergy to any of the agent or some kind of neuropathy. It would be great if you see treating physician as he will be able to examine and tell exactly what is happening. If allergy is there it can be treated with anti allergy drug and removing the offending agent. If you have neuropathy we need to know the cause like Nutritional, alcohol. Hope this information helps you. Take care Good Luck. Dr.Akhilesh Dubey M.D.
