I have blisters in my neck and buttocks. Is this Chlamydial infection?

Hi doctor,

I am a 39-year-old male. I had a body to body massage with a girl before three years and I had a chlamydia infection. I had some blisters near my bladder and I took antibiotics Azithromycin 1 g, Cefixime 400 mg, and Doxycycline 100 mg twice a day for 14 days. I took these medicines under the guidance of the doctor and treated them. Before two years, I had sex with a girl. After a week, I took the same course of antibiotics just as a precautionary measure. After a few months, I noticed some blisters on my right buttocks and it pained a lot while sitting. I also noticed some boils on the right side of my neck. I did not take any treatment for this till now.

Once I tried to apply turmeric cream over it and it resulted in severe itching. Though it stopped after a few days, I had some itching on the side of my right hip. I also noticed some skin burn on the right arm recently. Still, I have blisters on my right buttocks and I did not have any pus. There are boils still on my right neck. I am attaching the pictures. Recently, I took Doxycycline 100 mg twice daily for 14 days. I do not have pain while urinating and pain in the bladder or penis and there is no other discharge. I did HIV and STD tests. All the results came negative except for chlamydia. Does it indicate a past infection? Can I have chlamydia trachomatis? Do I need to get chlamydia real-time PCR to rule out the active infection? Please explain the reason for having boils or blisters and what causes them.

Thank you doctor,

I have boils in the neck region. Can I have it due to molluscum contagiosum? Earlier, I had it on my buttocks and after using a herbal soap, they got completely disappeared. Can it have spread to the neck? Can I have a skin problem due to the wrist band as I was wearing it near the elbow? I also have itching in some body parts. Could it indicate any disease? For chlamydia, does PCR test is reliable to rule out the current infection?
