Last Monday some pain in hip flexor area (tried something new at gym). AFter a week in the evening the pain increased severely and the doctor said its a hip flexor issue or tendinitis. X-rays were normal and he put me on the medrol 6 day pack 4mg. Pain is totally gone after 1 day. Today is day 4 of the steroid. Leg feels bit stiff and I'm scared of lifting it up as I'm worried pain might come back.. But I can definitely now sleep straight and walk straight as well without limping. Will the pain come back after the steroid runs its course? Will my leg stiffness ease on its own?
