thyroxine is a thyroid hormone. are you taking thyroid hormone pills?
there is no interactions between diuretic (water pills) like Lasix (furosamide) and thyroid hormone pills like levothyroxine or synthroid
these medications are safe to take together.
I am sorry you have broken veins in your legs.
veins can be injured through a long time of smoking or drinking alcohol or poor diet or lack of exercise.
you may have neuropathy in your legs on down.
you may benefit from nerve pain medications like neurontin (gabapentin) which could help your pains.
you could also be having claudiation pains in your legs from poor circulation. medications like cilostazol (Pletal) pentoxifylline (Trental) could help your pain and improve circulation.
talk to your GP doctor about these options.
