Do I really need to fast before getting tests for vitamin B12, vitamin D, CBC, and thyroid? I was told to get these because I'm dealing with hair fall, but I'm not sure if fasting is necessary. Can you clarify this for me?

For your tests related to hair fall, here are some key points to know about fasting requirements:

Vitamin B12 and Vitamin D tests: Generally, you do not need to fast before these blood tests. They can be done at any time of the day.
Complete Blood Count (CBC): No fasting is required for a CBC test.
Thyroid function tests: These also do not require fasting.

It's always a good idea to follow any specific instructions given by your healthcare provider or the lab. If you are taking any medications or supplements, mention them before the test.

If you have any other concerns or symptoms, discussing them with your doctor will help tailor the testing and treatment plan effectively.

I've been experiencing some weird skin rashes along with vomiting lately. There are these small red dots on my hands and under the palms, same with my feet. I've also been feeling nauseous and have headaches off and on. The rashes are super itchy, and on my legs, it even looks like mosquito bites, but I'm sure there are no mosquitoes around. What could this be? Should I be worried?

It sounds like you may be experiencing symptoms of an allergic reaction or a viral infection. The skin rashes, vomiting, red dots on hands and feet, nausea, headache, and itchy bumps on legs could be indicative of a condition like hand, foot, and mouth disease. I recommend taking an antihistamine like **Benadryl (diphenhydramine)** for the itching and rash. You can also consider using a topical corticosteroid cream like **Hydrocortisone** to help with the inflammation. For the nausea and vomiting, you can try over-the-counter medications like **Pepto-Bismol** or **Dramamine**. Make sure to stay hydrated and get plenty of rest. If your symptoms persist or worsen, it is important to seek medical attention.

I'm struggling with unwanted body hair and it's getting really frustrating, especially in areas like my underarms, lower abdomen, and butt. Shaving is such a hassle. Are there any places in Bangalore where men can get permanent hair removal treatments? I'm pretty anxious and would love some advice.

Yes there are successful treatment plans, visit Dermatologist for appropriate treatment

I have a skin tag near my anus and I think I might also have a fissure. Is there any way to treat this without surgery? Are there medicines or home remedies that can help with the pain and healing?

Topical creams, sitz baths, and stool softeners may help anal fissures and skin tags. If conservative treatment fails, minor procedures may be needed.
