I don’t think there’s any reason to go to the hospital at this time, unless you think it’s an emergency. But making an appointment to see your primary care physician would be a good place to start. After a discussion with the doctor they may order a few blood tests, which can reveal quite a bit about your health.
I can’t help but feel that seeing your doctor would give you some peace of mind. The symptoms are bothersome for you, enough for you to be concerned. Taking action can go a long way in helping you feel less anxious.
