My boyfriend started experiencing abdomen pain and pain on the right side of his midriff this January. He usually complained about feeling fatigue but we ignored thinking it's his schedule. With time the feelings increased. Lately, we considered multiple doctors and made him go through a lot of tests (LFT, KFT, Ultrasound of abdomen region, blood tests, CECT, Vitamin B1 and Vitamin D3 test). Mostly all tests came out to be normal, else than Vitamin tests where his B12 is 240 and D3 is just 22. The doctor recommended giving him Calcerol (60,000 IU) every alternate day. But he still feels the same. He constantly feels fatigue, complains of being in a dream like state, brain fogging, tired watery eyes, pain in various body parts and is always scared that he will never get better. Before this illness, he was a very bright and happy-to-g-lucky kind of a person but he is not the same anymore. He says his bones ache so much that he feels he might fracture them of over exertion. He keeps reading about diseases etc. on the internet and is going down the negativity trap. Has anyone of you ever had D3 deficiency? If yes, did you suffer from the same kind of things? How should we cure him and when will he get better? Please suggest. In dire need of advice.
