Irritated

So last night I planned to do a yard sale for this morning since my neighbors were having one. I spent about an hour pulling things together in the garage for the morning before heading in for the night. After a shower I watched a movie with my hubby while I laid down with a heating pad. The pain just kept getting worse and worse till I was in tears. I ended up crying myself to sleep since I couldn't get any relief from the medicine I took or the heating pad. I didn't get up to do my garage sale or do anything til about 9:00 that morning. I work up with my fingers hurting really bad. I moved slow today but didn't hurt to badly the rest of the day today. I get so frustrated because the pain gets so bad sometimes and I can't seem to do anything to make it go away. I pray and I try to relax but nothing seems to help. The heat and medicine don't  help sometimes either and I am tired of my doctor say to just lose weight because when I was in high school I used to hurt this bad and was under weight. I know I need to lose weight but that is not going to cure this. So what do I do from here? How do I live with this the rest of my life? I am praying for the answers to those questions.
