I have been diagnosed with high blood pressure about 3 months ago, after having a racing heartbeat. Was on 150mcg activas levothyroxine and very good tsh of 0.17. Saw Doctor and had to wear 24 hour blood pressure monitor, and average reading was 181. Was put on 5mg of Amlopodine for 2 months, and blood pressure was still 153, so it was upped to 10mcg. Doctor also reduced my thyroxine from 150mcg to 100 mcg a day. It was put back up to 12mcg after 6 weeks. I still wasn't happy with my TSH which was 2.8, so Doctor agreed for me to take 150mcg one day, and 125mcg the next. Being re tested in 6 weeks, and also for folate, as this has been picked up as being low. I have B12 injections every 3 months, and it is now 530. I am also on calcichew tablets. I am on activas levothyroxine, and wockhardt for the 25mcg. My question is that I have been having terrible pains around my elbow joints for the past month, which is getting worse. It started in my left one, and is now in my right one. I feel like my elbows are really stiff, and will not move properly, and also the muscles around the elbows as well. I know that being under medicated can do this, but can it be the 2 different brands of thyroxine. Or is it the Amlopodine. I have got an appointment for the Doctors next week, but can anyone help?
