On Monday I had abdominal pain and nausea and stomach upset.  On Tuesday I developed a rash all over my body that didnt itch and was not raised.  The rash went away in 2 days with antihistamines.  On Thursday my lower back started aching and it radiated down my legs and into my knees.  On Friday the back pain was worse and I was extremely tired and sore all over.  On Saturday my hands hurt and were swollen.  On Sunday my hands and feet were extremely swollen and very sore.   My jeans are very tight today as well and my face looks puffy.  I can barely make a fist with my hands and it hurts to type this.  I also have nasal congestion and a sinus headache now.
Hi ! You may be having some kind of viral fever which can give rise to such symptoms. You should initially get your routine blood tests done with special reference to the platelets including an LFT, Blood Urea and Serum creatinine. In some viral fevers, fluid gets accumulated in the body cavities and that gives rise to edema and swelling everywhere. Your abdominal pain and nausea could be due to deposits in the peritoneum and other intra-abdominal organs. The back pain which radiated down to your legs could be also due similar causes in the spinal cord. Also, the puffiness of your face and swellings in hands and feet could have a similar etiology. The nasal congestion also points to such viral cause of your problem. Please consult your family physician at your earliest possible. Wish you a fast recovery.
