<s>[INST] I have chronic urticarial. a few months ago I started an aggressive exercise regimen, running, weights, jumping, etc. I started to experience random tingling sensations in my legs and then I tried a stair master and after that I had a significant attack all over of tingling and pain on the bottoms of my feet (my dr. had diagnosed me with pressure hives/dermatographism 3 years ago. what can I do? I stopped exercising and its better but not completely gone. Certain ways that I sit can bring it on but if I get up and walk it goes away. [/INST] i think you should visit an orthopedic specialist. get ur spine assessed. as tingling sensation can be due to back disorder as you are even a heavy weight lifter.kindly visit and orthopedic specialist and follow the guidelines. you need to strengthen your core muscles and be little slow in performing exercises. </s>
