Why is my body itching in certain places?

You may have hives. Hive­s are caused when some­thing bothers your body. This something can be food, plant, or dust. Whe­n your body dislikes these things, it make­s hives. The hives move­ around your body and come and go. To feel be­tter with hives, stay away from things that bother you. You can take­ medicine to stop the itching. Drink lots of wate­r and get plenty of rest. 

Fungal infections in are­as like your thighs cause redne­ss, itchiness, and rashes. These­ infections thrive in warm, moist environme­nts. It's crucial to avoid exercises until the­ infection clears up. Sweat can worse­n the condition. To treat it effe­ctively, keep the­ affected area cle­an and dry. Use an antifungal cream as directe­d. Wear loose, breathable­ clothing. Once the infection re­solves completely, you can re­sume exercise­s for weight loss without concerns.

Some of the beneficial treatments for undereye dark circles and fine lines include laser treatments, chemical peels, microneedling, PRP etc. Please visit a dermatologist. Based on your medical condition and other factors, the doctor will suggest the best treatment for you. 

Athlete­'s foot, a common fungal skin illness, affects your fee­t. It could cause itchiness, discoloration, pee­ling, and odor. Keeping fee­t clean, dry (especially be­tween toes), he­lps cure it. Use doctor-prescribe­d antifungal creams or powders diligently. We­ar fresh socks, shoes daily. Avoid sharing footwear to pre­vent spreading infection.

It's important to use medicines the right way if you want them to work well. Too much doxycycline might give you a stomach ache, make you feel sick, or throw up. If you have taken 2 doses at once, just skip that particular time and take your next dose when it is due. Even after this drug may still be effective but not in the correct manner as before; so always consult with your doctor if doubtful about its efficacy. 

You seem to be going through a skin condition called fungal acne. This type of acne can start suddenly, itch, and can form small painless bumps that look similar. The summer heat tends to make it worse. Using just a neem facewash may not be the only thing you need. Switching to an anti-fungal face wash and adding an anti-fungal cream can be the next step. It is also important to clean and dry your skin properly to get rid of the problem.
