Psoriasis? (Doctor not an option)?!

Psoriasis? (Doctor not an option)?

I obtained a rash a while back. First it started out as a bunch of bumps and every time i would get stressed out they would itch like crazy. I've tried every over the counter med i could think of, nothing works. I try to keep my stress level under control but life is life and i can't always control it. It's embarrassing. I never go swimming anymore, i miss the skin i used to have, it was so clear and smooth and now its ruined in patches here and there. I know it is psoriasis though, it runs strong in both my parents and looks just like theirs. Now it constantly itches, im in constant pain, especially taking a shower, it burns like none other. I dont even know if i should keep it moist or dry because both seemed to make it worse. Covering it made it worse too. I can't see a doctor, can't afford one. And my parents just let theirs go so they have no advice for me. any help whatsoever??

After I take a shower, I don't dry myself off. I apply Desitin to my body. Desitin is baby rash cream. But it is 40% Zinc. (Make sure you read the back of the label and buy the one that has the most Zinc) Zinc helps in healing wounds. It's what they use in the nursing homes when patients get bed sores. It will help heal your skin and keep your skin well hydrated. It's terribly sticky and an annoying to apply, but it works. Also, applying lotion just keeps your body from letting moisture escape. But if you don't have very much moisture in your skin, it won't help. So if you apply lotion when your skin is wet, the lotion traps the moisture.
