question: I, Hispanic male moderately active w/high blood pressure risk being only thing treated, developed hyperthyroidism 3 years ago at age 60. In denial for some months after until I could noticeably feel my heart beating in an irregular manner. When I went to my GP I was referred to 2 specialists- 1 cardio & 1 endocrine. Within 2 months I had undergone heart related stress tests, echo and monitoring while taking the Rx Pradaxa to reduce any possible unknown risks. At the end of the 2 months I had radiation treatment for the thyroid. It took about 7 weeks to regulate my thyroid with synthrax. I requested an alternative to pradaxa after seeing a bad drug commercial and was placed on warfin, 1-2x a day dependent on how I feel. Not having specific dosage plan landed me in the ER where I was admitted and given blood transfusion within 2 hours of arrival! I continued to visit ER on 3 separate occasions that week. Had an overnight stay on 1st visit where I was monitored, provided all needed remedies and blood was tested for the Immediate end of warfin use, of course. After 1 week I saw cardio and he prescribed Xarelto for my AFib. Although I was afraid I complied with the doctors request, the very same Dr that prescribed warfin. I have taken xarelto now for over 2 years and at a cardio checkup nearly 6 months ago he tells me that my AFib is no longer heard and wants to do the same tests performed 3 years ago to confirm before taking me off the medication. The tests are completed, confirming his diagnosis that my AFib is no longer present- yet I am still on the medication and have visited him more frequently than with the condition. Is there a medical reason for this? I am now experiencing upper left arm numbness for a noticeable period of untimed minutes 2 or 3 times a week. What could be the culprit- warfin long term effects, xarelto taken for non existing condition, possible stroke or any other non related med issue ie back or activities? I do not want another adverse reaction caused by this secondary and now non apparent issue. What can or should I do? Also take 1 lisprinol for hypertension and 2 500mg Tylenol 2-3x a day for arthritis.
