<s>[INST] Hi,I am 25/M feeling terrible chest pain in addition to chrohns disease, high cholestrol,high BP Doctor diagnosed me to be of Vitamin D3 Deficient. Please suggest is this terrible chest pain is only due to Vitamin D3 deficiency(less than 4). Even I am being administered 60000IU / week for 6 months. I have taken 3 doses upto now but there is no relief in chest pain [/INST] Thanks for your question on Chat Doctor. I can understand your concern. No, vitamin D3 deficiency can not cause this kind of severe chest pain. Most common symptom of vitamin D 3 deficiencies is bilateral lower limb pain. And after 3 doses of vitamin D 3 you are still having chest pain, so in my opinion we should search for other cause for your chest pain. Better to get done ECG, 2d echo and chest x-ray. If all these are normal then no need to worry about heart or lung related diseases. Apply warm water pad on affected areas. Take simple painkiller and muscle relaxant Chat Doctor.  Wear rib belt. Don't worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
