First step to padel elbow by overuse. Ice, rest , massage, stretch, isometric holds. Ibu, Diclo, Naproxen, Curcuma could help ( dont take those before a match, because ypu will overuse the arm).
If you need to play, use a light, soft racket, play social matches in a controlled way. But somedays with light cardio 15 mins ( eliptic, rowing) could be better ( blood flow through elbow).
Use a soft wrist bandage without plastic splint. 1mm or 2mm neopren could help.
Could be caused by backhand or smashes ( overheads with wrist).
