10 Best Hematologists in Dubai

When the small lymph nodes which are like little bumps show up in the armpit, they could be caused by infections such as a common cold or a cut on your arm. The nodes are part of your body's immune system and help to defend against viruses and bacteria. If the nodes are swelling or you have any discomfort, it would be a wise decision to see a doctor. They can provide suggestions for strengthening your body's resistance. 

Swelling in lymph nodes within the chest can arise from various factors, including infections, inflammation, or occasionally more serious conditions. Common accompanying symptoms may include coughing, pain, or fever. It’s essential to monitor any ongoing issues, such as persistent swelling or discomfort. Starting with rest, hydration, and over-the-counter pain relievers can be beneficial. However, I recommend consulting a hematologist for a thorough evaluation and tailored guidance, ensuring your health is prioritized. 

The symptoms you mention - rashes, red dots, hot sensation, and shortness of breath - may be caused by various reasons other than HIV. For instance, stress and anxiety are also potential causes of these symptoms. To be sure, you can ask a doctor.

Low blood volume, or anemia, can cause fatigue, weakness, and dizziness. Possible reasons include chronic blood loss, nutritional deficiencies, or certain medical conditions. It's important to increase your iron intake through diet—consider foods like spinach, meat, and beans. Staying hydrated is also vital. However, given your symptoms and recent diagnosis, I strongly recommend following up with your healthcare provider for further evaluation and a tailored treatment plan.
