Do I have scabies?

[ogz64024]

A month and a half a go I started getting small red spots or pimples or rash on my skin that itches a lot. It started to spread and spread mostly between my knees and my stomach. Most of them are on my thighs, buttcheeks and groin or rather areas converging these three. I have some on my genitals too. They itch like crazy during the night and I cannot sleep. So I went to the doctor and...
Scabies takes 2 to 8 weeks to show symptoms right? Well I have actually calculated and re-visited all the time I apparently got infected. Truth is I never: Slept in someone's bed, had sexual intercourse or any intimacy, wore someone's clothes, I barely hugged anyone and those I hugged are close family members highly unlikely they are infected, I didn't even handshake that many people. I only wrestled with a younger cousin of mine who had issues with some rashes on his skin, docs in two countries told him it was allergies and anti-allergy medications helped him and it seems like a mild annoyance for him, when I was with him it was in late December, but other family members did it too(wrestle) or cuddled with him, and since they or he have no scabies...

So the symptoms on me started to show roughly on the last week of January or first week February, that would mean that by now I am having scabies in full form for more than a month, and yet no family member of mine has shown any symptoms. My brother who even shares a room with me, who's bed I was in a few times, who also shares a chair with me has shown no symptoms yet. Now what me and my brother do both have had is symptoms of cold, or simply a cold. Only he had it a bit worse, with maybe even some higher temperature while I was mildly annoyed by cleaning my nose. We both started working out a lot so I guess its the immune system being on pressure.

My physician/dermatologist was equally confused by this, but she still insisted. Although she didn't take any sample or even bothered to closely look at my skin. At one point she even didn't see the obviously huge red on my skin, that I was showing her. She insists I do not shower or change much my clothes for the next 6 days, while I have to apply some fat/cream up to my neck. I have read online a lot, and most of if not all treatments allow for shower and occasional change of clothes, so I am perplexed there. Why would she give me the harder treatment, the one which really forbids me doing any work or workout.

As for the work out, I started some kick-box, which means I barely touch anyone else body with mine or any other object and I always shower after training, and I never see anyone scratching or having symptoms of scabies in the gym. I am also sweating profusely doing workout, maybe that's not such a good breeding ground for the initial infection? I also cannot remember that clearly, but I think my symptoms started a bit before the training or really early in the training.

So as you can see I am really afraid, nervous and confused, I am at odds should I spend more money on visiting another town or a private dermatologist or just argue more with my old one.

I was reading the article about scabies, it didn't say anything about not to shower for the next 6 days. This is what it said:
1. Apply a mite-killer like permethrin (Elimite). These creams are applied from the neck down, left on overnight, then washed off. This application is usually repeated in seven days. Permethrin is approved for use in people 2 months of age and older and is considered to be the safest and most effective treatment for scabies.
2. An alternative treatment is 1 ounce of a 1% lotion or 30 grams of cream of lindane, applied from the neck down and washed off after approximately eight hours. Since lindane can cause seizures when it is absorbed through the skin, it should not be used if skin is significantly irritated or wet, such as with extensive skin disease, rash, or after a bath. As an additional precaution, lindane should not be used in pregnant or nursing women, the elderly, people with skin sores at the site of the application, children younger than 2 years of age, or people who weigh less than 110 pounds. Lindane is not a first-line treatment and is only recommended if patients cannot tolerate other therapies or if other therapies have not been effective. Resistance to this medication has also been frequently reported.

Scabies are very common and it's treatable, since you already on treatment then you shouldn't be worry too much. I think you should just wait and see after the treatment has completed, if it's effective.
