You need an exam: Without knowing your medical history, nor the ability to ask you questions and examine you, it would be inappropriate to give give you a long list of possible causes for your symptoms, which would just worry you. You need to see a physician for an exam to diagnose your problems(s). Don't try to diagnose yourself via the internet, you won't be able to. Sorry we couldn't help. Get well soon.
