I have pernicious anemia an..

My stomach is bloated and it feels like there are lumps under the skin particularly at the top of my stomach (under breast bone - in the middle) Do these gastric problems relate to the pernicious anemia? I am also hypothyroid (on medication) have had a parathyroid tumor removed and have mild vitiligo

First of all you need to get the B12 shots on a regular basis. You need to keep your hemoglobin at a healthy level. This is just as important as taking the thyroid medication. The bloated stomach sounds like you might have an ulcer. If you do and they find out you have the H. Pyloric bacterium, you can be treated with antibotics to get rid of it. Then take prilosec to heal the ulcer.

The lumps could be sebacious cysts, but you really need to see your doctor to find out. Good Luck

Go see the doctor right away. You need to be seen asap. Tell the doctor about this and ask him if they are lymph nodes.
