Hello and welcome. Firstly I would suggest you to visit your physician. The lymph node swelling need to throughly examined. Blood tests will needed as well some x-rays. Lymph nose swelling are usually infectious in origin. For headaches and joint pain you can take combi flam or diclomol tablets twice. You also seem to describe some fungal lesions. With over the counter antifungal preparations they should be fine. If they persist or worsen oral antifungal medications may be needed. Meanwhile you should try to keep up your health and immunity by taking good nutritious food, and rest. Hope I answered your queries. Thank you so much. Take care.
