After reading the different comments there seems to be a pattern or at least a possible connection - fibromylgia - sarcordidosis - lymphoma. I, unfortunately, have had these and in visiting with other patients while waiting to see the doctor, find this is more common that we would want. So much progress has been made in the last three years, so if your doctor is older or doesn't keep up faithfully with new data, don't hesitate to see someone else. I know it is of little comfort, but there are many of us in the same boat - don't let anyone convince you "it's in your head" or chalk it up to being a woman. Much relief, even though it is temporary, can be achieved with warm water exercise. I go several days a week and some of the other ladies go every day - it certainly won't hurt you, and any relief will be welcome. Don't give up. Take care, good luck, and may God bless.
