Hi, thanks for your query.
You seem to have folliculitis
or boils on your hips.
Sweat and moisture in this area facilitate the growth of bacteria leading to infection. Prolonged hours of sitting aggravate the condition to formation of abscess
. Avoid sitting continuously for many hours.
Since it is a huge abscess, it needs to be drained by a simple non invasive procedure called incision and drainage
under the cover of oral antibiotics
from a surgeon.
Also you have mentioned that you feel tired all around the day and need lot of sleep, you may get your thyroid
Hope this solves your query.
You may right back if you have further queries in this regard.
