Hi, I had gone through your question and understand your concerns. Yes a vitamin D3 level of 9,9 is quite low.The normal level being 30. I would suggest you to take the arachitol injection 2 of which are left and the Cholecalciferol capsules for 6 more weeks. Get a vit D3 level done after completing this course. About the erythema multiforme, I would advise you to continue the Betnesol. Your doctor will continue to taper it off. The TSH level is not a thing worry. I would suggest you to keep in touch with your doctor. He/she can examine you and correlate clinically. Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health.
