I have suddenly allergies and itching has started all over body. I have started getting rashes as well after my dinner. However, I get allergies very easily and frequently. Also, everyday morning I get up with severe back, body, head & throat pain with broken voice. With time passes things get little better, though body pain, tiredness & headache stays with me. I feel loss of appetite, low energy & mood swings also happens a lot (sudden anxiety, irritation, disappointed, sadness) & random food craving stays with me. At night while sleeping I get very bad leg pain as well.
