I've been researching fibromyalgia. I believe I have this. I have no insur. Is there anything over-the-counter I can take to help me? Help please

See below. Gentle exercise is the key. Stay active. Oral nsaids may help. Get enough sleep. Eat a balanced diet.
Not a psych disorder. I would start with a primary care physician. Fibreomyalgia is not a psychiatric disorder.
Non steroidal. Antiinflammatories like Aleve or ibuprofen, tylenol, (acetaminophen) sleep aides like melatonin are available over the counter. You need to try and stretch as well as walk/ exercise as tolerated. Best of luck to you.
