My husband has been suffering with thigh pain for about four or five days. It started as an ache, feeling like a pulled muscle and developed into sharp pains in his upper leg. For. The past thirty six hours it is a dull, persistent and painful ache. He finds it difficult to weight bear . He is also feeling very tired and is generating a lot of heat from his body as if he has a fever but doesn t himself feel feverish. He suffers with RA and takes large doses of methotrexate. He also has mild diabetes which is stabilised with medication. We are presently on hols in Australia and he flew here from the UK two weeks ago. He is aged 64 and weighs approx 17 stone. He is circa 5 9 tall. Any ideas or what should we do?
