I am female 35yr old .About one and half month back,I was feeling cramping pain in my lower limbs just like that of period pain along with whole body pain and weakness. I got my vitD3 level 8.16 ng/ml.The doctor adviced me 3lac I. u vitD3 I. M and told me to take next dose after 30th. At same time my TSHLEVEL, T3,To level were .85ng/ml,7.3micro g/dl,5.43microIU/ml.After about 1 days I started radiating pain from pelvic region to above left knee.My doctor adviced USG which report was b/l mild dilatd pelvicalycealsystem (nonspecific? ).I was given 6 lac i.u vitD3 I. m and he told me to take 3 more doses of 6 lacI.mvit D3 at interval of 15days.The pain disappeared after one of taking in of vit D. Again I got myT3,T4,TSH level as1ng/ml,5.8 micro g/dl ,5.12microIU/ml.I no no my own or any family history of hypothyroidism. Does this high TSHLEVEL level is due to low vit D 3 level? I have just started taking thyronorm 15th idly for 4 days.Also please tell me does the radiating pain in my left was due to vitD3 defiency? Also tell me that should I take other 6 lac i.u vitD3 at intervalue of 15days without checking blood level of vit D3 ?Upto what level of vit D 3 should I take inj of vit D3?I always feel fatigubility without any reason ,my Hb level is 12g/dl.
