Brief Answer: Follows Detailed Answer: Dear Sir, Thank you for posting your query on HCM. Well looking into your problem I would like to tell you that it will be very difficult to say anything on your symptoms but still we can discuss the possibilties . One is Gout , it can present like this so there is a need to get serum uric acid levels tested . Other can be spondyloarthropathy which can be triggered by a urine or stomach infection . Plus if you have a history of psoriasis or anybody in your family has it the likelihood of getting this kind of picture increases . I think you should need to see a rheumatologist for this because examination is very important to see what is actually going on . Till then for pain relief you can take naproxen tablet if there is no contraindication for that. Take care. Dr. Shruti
