It's scabies. You need a prescription for Permethrin 5%.
Wash bedding, towels, clothes in hot water. Take a hot shower every day.

Have had these very itchy bumps on the upper surface of the foot, ankle and lower calf. Usually only in the winter months, but the most unusual symptom (along with some of the other posts) is that the itching occurs at night and has woken me on occasions. Sometimes the scratching will severe and cause surface abrasions.
Also as biged44 describes, when the bumps stop itching the bumps fade to dark spots. Whereas I don't know for certain what the cause is I have found a cure. After washing with soap or after a bath rub Nappy cream containing zinc oxide all over the area. You'll find you get some relief on the first night. Wash and reapply every day for a week and you should be OK. Then if it recurs do the application of zinc oxide cream straight away and the bout of inching will be minimised. Post back on this thread if it works please.
That would make you think it is a fungal infection, but the way it happens at night sounds a little like Demodex mites.
Hi,
Scabies usually presents as small red bumps and blisters that may be found between the fingers, the wrists and the backs of the elbows, the knees, around the waist and umbilicus, the axillary folds, the areas around the nipples, the sides and backs of the feet, the genital area, and the buttocks. There is also the presence of "burrow" or tiny threadlike projections, which are often mistaken for linear scratch marks that are large. Scratching actually destroys these burrows. The itch of scabies is insidious and relentless and is usually worse at night.
We may also consider other causes such as hives, eczema or dermatitis or other insects such as bedbugs. Over -the-counter antihistamine may be helpful at night. If it persists, it would be best to have this evaluated further for proper diagnosis and management.
Take care and keep us posted.
