What might this be? an itchy rash like cluster of bumps on my lower back just above my buttocks. It looks a lot like a bunch of mosquito bites.

How long?

If it lasts over 6 weeks, see an allergist. If it is short term, try some OTC antihistamine up to 4 x the regular frequency but watch out for drowsiness. Otherwise topical hydrocortisone cream should be tried. If it still did not work, see an allergist.

I have a bright red (and itchy!) rash on the back of both my legs, between my butt and knee. It looks like small bug bite like bumps. Not spreading.?

Bites

Contact_dermatitis
The toxins that are injected from a bite can easily cause a local numbess and skin changes. Bites usually just cause local swelling and redness in the soft tissues.

Many bright red and itchy rash on the back of both my legs, between butt and knee. It looks like small bug bite like bumps smeared in a line. NoSpread?

Many causes

Leg
Rashes are challenging even when the doctor can see them, so even harder in this forum. Small red bumps on both legs make me think of reactions to clothes, or something in contact with that area on both sides. Bites can do it. It could be heat rash, a reaction of the skin to warmth and occlusion from pressure. Some drug reactions can do that as can conditions like eczema and psoriasis

Itchy rash on back of neck and in hairline also on lower back?

Itchy back

Rash
You might be allergic to your shampoo or another hair care product. Without a medical exam it would be difficult to say. Consider using only a non sensitizing shampoo such as Free and Clear and avoid other treatments. If that doesn't work seek out a board certified allergist or dermatologist.

Psoriasis?

Psoriasis involves both these areas and could fit with this description. There are many different prescription creams as wells intralesional treatment which can help this condition. An effective over the counter product to alleviate the symptoms is scytera foam. If the response is inadequate see dermatologist for evaluation amd treatment.

Pruritic urticarial papules and plaques of pregnancy. Very itchy rash (pruritic) begins in stretch marks on belly with small, red wheals that grow together and over several days, the rash spreads to thighs, arms, & buttocks. The condition is harmless to mother & baby, but can be very annoying. It lasts about 6 weeks and resolves spontaneously 1-2 weeks after delivery. Go to OB for treatment.

I get a really itchy rash consisting of lots of small bumps on the roof of my mouth and towards my throat.most itchy when they appear.ideas of causes?

Itchy palate

Pruritis
It could be allergies. Have you been treated for or diagnosed with seasonal allergies or an allergic reaction to certain meds. Gilberts syndrome does show the potential for itching w/o rash. I woulod consult your physician to determine if any further testing is necessary if it is something that happens frequently.
