I am 21 pregnant currently weigh in at 143 and i am 5 2 in height maybe even 3.. I have just noticed within the past 3-4 days that I have a small bump maybe the size of a jellybean under the skin located just beneath my tailbone in the crack of my anus. On top of this bump are 4 pinsized holes out of one of the holes after applying pressure to the bump a whitish-yellow puss like liquid came out slowly it carries a foul stench. This stench is also present in my vaginal discharge now when i use the bathroom. The bump is very painful and I can not lie down on my back nor sit up straight without experiencing a pestering pain. I stayed up all last night b.c any slight pressure put onto the bump triggers the pain and increases its intensity. I often have problems in this area since being pregnant where I feel it is raw due to rough surfaces, such as toilet paper and washcloths. I am not sure what to do I really can t take this on top of already existing symptoms of pregnancy. Please help!
