Suggest Help With Severe Tailbone Pain, Protruding Bones On The Cervix, And Extremely Dry Skin After Gastric Bypass Surgery

Hi, I had gastric bypass surgery in 2003 and have had a lot of problems since then! I recently in the Fall 2020 lost another 50lbs as I was always sick with nausea or pains in my stomach. Anyways, I am 5ft 3 inchs and weigh 95 lbs. My Problem is my tail bone, it has been sticking out, and almost tearing my skin it is hard to sit, I am always in pain. Is there any Doctor that can help me? I also developed all little bones sticking out on my cervic, and are very painful! I also have severely dry skin, and my skin feels like it is going to rip open. I have been suffering for over a year. please email me. Thank You!
