It sounds like something you need to get checked out. As far as a place that won't cost you an arm and a leg...not sure. What I do recommend it looking into AHCCS (the Ariz. Health Cost Containment System). You and your husband might make too much to qualify for no-cost insurance, but there are different plans you could qualify for very little every month. I hope that your swollen gland is nothing,and I don't encourage others to be fearful, but making sure your family is covered for emergencies is crucial. I know how hard it is to give up extra money every month for health insurance, but it is much much better and smarter than losing everything due to overwhelming amounts of medical bills. Also, if you have some type of insurance BEFORE you get checked out, it will be easier for the company to cover any other costs if more medical attention is neccessary. Many times if you don't have insurance and are diagnosed with anything, it's like pulling teeth to get an insurance company to cover you with a "pre-exixting condition". It's ridiculous...insurance companies own us I think and I wish more holistic practitioners were covered by insurance...but for now, we need to cover our arse.
Best wishes and I hope you start healing very soon.
PS. You could also look into paying for a visit with a Naturopathic Dr first. Usually the visits are less expensive and more often than not, treatment is less invasive and treats the whole body and underlying conditions...not just the isolated condition.
