Moved to high desert 2 months ago in Central Oregon- have had pressure in chest for one month and feeling tired- got bite on leg when first here, thought it was a spider bite. I am in good health, take no medications and am almost 63 years of age. Probably not related, but our Maltese dog just tested positive for Rocky Mountain disease. Thank you for your help, as I have not found a physician in my new home town yet.
