Swollen lymph node in hip.?

I've already been to the doctor once because of this, they cut it open and drained it, gave me antibiotics and it went away but after a week, i ended getting sick and wasn't able to hold down any food or liquids and was constantly going back and forth from feeling too hot and too cold, i also started having severe abdomen pains so i went back to the doctor and found out i had an infection in my colon as well.

Now a month later the same issue with my hip is back, i'm taking antibiotics again but its not going down and i'm slowly starting to get abdomen pains again and my appetite is slowly vanishing. My hip is inflamed,swollen, extremely red and also looks kind of like a slight bruise. It's very painful to touch and it hurts having clothing items even slightly touch it.

I'm a bit scared at this point and I don't want to go back for them to just drain it again and put me back on antibiotics if it's just going to return (I understand that it can take months for it to completely go away but it's only getting worse).
