Suffer From Pain In Calf Muscles. Having High Blood Pressure. Taking Atenolol, Bendroflumethiazide And Cetirizine. Guide?

Question: I am 61 male and have been suffering from pain in my calf muscles over the last month or so. seems worse in morning when I have been inactive. I have high blood pressure that has been successfully controlled by medication for some years. my medication includes: Atenolol 50mg one taken in morning, Bendroflumethiazide 2.5mg 1 tablet each morning, cetirizine 10mg one daily, Doxazodsin 4mg 1 tablet each morning. I had a successful hip replacement two years ago. I have been experiencing arthiritic symptoms in my hands the last 12 months and one of my fingers has a small hard lump that has developed. My concern and question is: I have developed strong pain in my calf muscles over the last month or so that is miserable and is effecting my daily activities. The calf muscles hurt more as pressure is appllied through massage. I have taken ibuprofen and massage ibruprofen gel into the calf muscle. The pain is worse in the morning after inactivity. The pain seems to be constant although I cope better when I am doing things to take my mind off it. are you able to suggest what this may be, the cause and treatment. Many thanks
