Unrelenting Pain

My body has been aching for three days now. The pain in my stomach is unbearable. I do not know what is wrong. I've been crippled on the couch, warming up heat pads to place on my lower back and stomach area. I feel a fever rising from all of the heat I'm administering to myself. I don't believe in medicines, but I forced myself to try an Advil today. It only made me nauseous and brought no relief from the pain. My back is drenched in sweat from the hurt. I hate feeling like this. I've lived on toast for the last three days. My darling animals have received no attention except for regular feedings that I force myself to get up for. I dearly hope the pain goes away soon. I can't afford medical treatment. And my herbs and home remedies are doing me no good.
