[|AI|]  Thank you very much for contacting Chat Doctor. Don't take Evian capsule without doctors suggestion. You don't mention which type of skin problems you have. You have severe back problem that is because of vitamin d deficiency. Sun rays are best source for vitamins d. Check your calcium level also. Sometime vitamin d and low calcium level may cause back pain problem. Nerve compression or injury may cause this problem. MRI is helpful for further diagnosis. Take more milk and green leaf vegetables. Consent a physician for further treatment. I hope my guidance is helpful to you. . Take care. Thanks.
