Help With Tremendously Awful Muscle Pains And Aches?

Hi , i used to go horse riding all the times years ago and then i stopped, then yesterday my friends (who has her own horse) was looking after someone elses horse because the owner had gone away on holiday. So we went on a 3 hour hack, very long, very tiring , and i think that because ive not done it in so long, this is why i am in AGONY this morning. The tops of legs, my bottom, my stomach area, my back , my arms and my shoulders , it is soo painfull i dont think ill be leaving the house today , PLEASE tell me there is something i can do or take to ease the pain, is there any special medicence designed exactualy for this or am i best off with Paracetamol or Ibuporfen , Thanks x
