Levoxyl and mental acuity

I WAA DIAGNOSED WITH HYPOTHYROIDISM 3 MONTHS AGO AND WAS PLACED ON LEVOXYL. PRIOR TO TREATMENT I WAS EXPERIENCEING MUSCLE FATIGUE, OVERALL FATIGUE, WEIGHT GAIN, SHORTNESS OF BREATH, JOINT PAIN AND LOSS OF MENTAL ACUITY. SINCE TAKING THE DRUG, I FEEL MY MY MENTAL CAPACITY IS BACK AND A LOT OF MY FATIGUE IS GONE, HOWEVER, I AM RETAINING HUGE AMOUNTS OF FLUID EVEN WITH A DIURETIC, DRY SKIN, HAIR LOSS AND MOST RECENTLY A RASH WHICH STARTED ON THE FRONT OF MY CALVES AND IS NOW ON MY NECK, ABDOMEN.
