It looks like a swollen lymph node or a boil. A boil generally starts as a reddened, tender area. Apply warm compresses and keep the area clean. Also apply a topical antibiotics cream like Neosporin or Mupirocin. Drainage of the boil is done only when it becomes soft and forms a head. Take some over the counter pain reliever and consult a doctor for examination and antibiotics prescription. If you are sexually active then herpes should be ruled out.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Thanks for your information. The area didn't start as a reddened area, the lump could be felt but not seen, it became painful and started swelling after a 2 hour car ride and after the swelling it became red. The pain when laying down is like a constant pinch & when sitting it's like sitting on a sharp golfball. I am trying warm compresses, I will get some Neosporin to use and have been using OTC pain relivers.
Unfortunately I am trying to avoid going to the doctor due to the fact that I have no insurance and the only other place I have available is my local ER. I understand that without an exam I can't be diagnosed but I do greatly appreciate the advice and will try this & of course if it doesn't start improving soon or gets worse I will be forced to find a doctor accepting new patients (which are limited in my area since it is VERY rural)
A boil generally starts as a reddened, tender area. Over time, the area becomes firm and hard. Eventually, the center of the abscess softens and becomes filled with pus. Finally, the pus "forms a head," which can be surgically opened or spontaneously drain out through the surface of the skin. So chances are there that it can be a boil or a cyst.
Try the above mentioned treatment and if the symptoms persist then get an evaluation done from a dermatologist.
I hope it helps. Take care and regards.
