Foot arch symptoms and conditions

I had my kenalog injection over a week ago. The winds here in the desert have been horrible this year and i was experiencing a daily sinus headache and my allergies were beyond what a claritin, allegra and a sudafed combined could combat. Within a day of getting an injection in right butt cheek area all of my sinus problems have ceased. Day three i stopped taking all of my medications for my allergies. I was also able to stop taking an anti inflammatory for my knee and the arches of my feet. They have never felt so good. My excema and asthma symptoms although mild have also cleared up. On the down side. I seem to be eating like a horse, insomnia and wild dreams seem to be plaguing me. But this is also the case when i take prednisone. I had this shot a few years back for the knee and foot arch pain and back then before my hysterectomy i did experience break through bleeding on my birth control pills a week early and very heavy. i decided that was the worse of my side effects back then. now that i wasn't able to have that problem i figured lets go for it again since i recall my sinuses clearing last time too, which was a bonus side effect for me then. overall i have found the positive effects definitely outweigh the negative effects for me.

Pain under toes, ball of foot, arch and pain traveling up leg calf. After stoppage of 4 months still have not gotten any relief. Gotta be a better way, because the side effect of constant pain, is only raising my blood pressure
