Help!! I was having a rare pain free week so being the sensible person that I am, I have played tennis 3 days in a row. I was doing ok. I did mtx inj as usual last night and now, boom...I've just finished the third game in a row and I feel like death. Sick, headache, cold, weak, pain everywhere😞. I've got to go to work in a couple of hours and I'm supposed to be playing again tomorrow but right now, I can't get out of bed!!!
