I keep suffering with joint pain in my hips, ankle and now shoulder which starts and a few days later an itchy bumpy rash appears on the joint that hurts. It then settles and then starts again a few weeks later, I visited my gp but they said the rash was probably an allergic reaction and gave me itch cream. Does anyone have any ideas what it could be please? Googled it and arthritis came up, I struggle to sleep for more than 3-4 hours from the pain and feel tired a lot of the time.
