I have recently been diagnosed with fibromyalgia. My mother and two nieces have it. The systemic pain was dramatic and any small amount of exercise would cause a flare up. My world became narrower and narrower trying to manage the pain. I did not want pain to be my master but little by little I withdrew from friends and activities. I live near Yosemite National park and love to hike. Oh how I miss it! Last week I went to my family doctor and asked him to prescribe phentermine because of the weight gain over the last six months. From the very first pill I noticed a reduction if pain. On the pain scale I went from a 7 to a 5. Day two, I went from a 5 to a 2. This was so manageable. Day three. NO PAIN!!! I have energy, I am dropping weight, I am gardening and I am socializing. YIPEE. I was amazed and grateful. I was not aware the Phentermine was used for pain. Has anyone else had this experience?
