I Have Been Taking Oroxine Tablets For About 11 Months

I have been taking oroxine tablets for about 11 months i have lost weight but i have been watching what I eat. i have noticed that from the knee up to the top of my leg there is muscle but drooping muscle lump.
I am also on hypertension tablets as well. Do you think its because of my thyroid problem this has occured
I am due for my next blood test the previous blood test about 3 months ago showed my thyroid was still not good so I was reduced from taking one tablet a day for 7 days to 1 tablet a day only 5 days a week.
Could it be from this? Or perhaps am I getting to a diabetic stage?
