We've just completed two weeks of swimming lessons here with the kids. They are held at a beach & after the kids have lessons we often go swimming. Last year the fibro was so bad that I only went 2 days out of 10, my hubby taking them the other days. This year I only missed one day. The only really bad thing was unfortunately the sun gave me wicked headaches Anyways out in the water one day I had Ethan (our 3 1/2 year old,) with floaty rings on propped on my hip, or holding onto my right arm, & my 3 year old niece in a floaty ring (waist ring,) on the other. It was quite a challenge seeings though any usage of my arms puts strain on my chest muscles & then I have trouble breathing. But we managed to stay in the water for ages. About 3 days after lessons stopped I noticed a new pain in my arms. It feels hot & tingly like sunburn but under the skin. It was really bad in the right, & not so bad in the left. It's been constant now for the last week If I move my neck a certain way it intensifies I get terrible arm pain, usually in the joints, but this is all over my arms just under the skin. Anyone else get pain like this??
